The porosity of these newer CF-2000 is such, that even when an .8mm gap between the wick and the wickhole exists with the fillscrew installed, when laid down flat, does not leak all day, and vapes as good as if the fill screw were off.

I shaved another of these CF-2000 wicks down slightly to 3.0mm for my other 9/16 genny ... similar thing, fillscrew installed, .6mm wick/hole clearance, enough air gets up easily while vaping to the max ... doesn't leak when positioned horizontally either.

7/64 for the 3.2mm ZAP wickhole will do, plenty of space. Probably why they started to make that size.

Ahh so the ZAP is 3.2mm. I wonder why the Cobra's is so small? I guess I shouldn't complain since everyone seems to like the 3/32 wick (even if they were hard to manufacture).

Worked up the stones to set up a 3/32 wick in an AGA T+ today. Found the hot wrap too fiddly with the 0.5 ribbon and so went at it with the original VapD method and it came out really nice :). I have to agree that there is a difference. Just loving the the flavor and the vapor and once again, no break in required and, it reaches temperature very quickly. A few toots and I am already at 14 watts on a 1.3 ohm coil and it is moist and juicy. Really had to be careful balancing the tension on the coil when tightening but it is in there safe and sound now and pumping away beautifully (just using the stock bits and pieces). And surprise, surprise, no hot leg at the top, lol.

EDIT: Really need to open up this airhole a little to get this thing to full potential. I think the AC9 has shown me a better way.

I think it was mentioned the ZAP wickhole is 1/8 inch in diameter, which is approx. 3.2 mm.

I'm not sure if any consensus exists what the best wick size is. I'm not a low-resistance vaper, so what I might prefer might not be the most optimum set up for them.

For me anyways, a 3/32 wick is dicy for hand-wrapping esp. for noobs. Too easily broken. There'd be too many user complaints requesting ~ZEN to enlarge the hole and use larger wicks. Many advanced users would have no issue with that size because they EHW hot-wrap, but they would be the minority in the marketplace, not the mainstream public. Then there are others like me who prefer electrically annealed handwraps for wicks 1/8+ up for yet other reasons, since I'm not a low-ohm vaper. People contribute their ideas here, and the more we have, the larger the pool from which you can draw from that suits your tastes.

I know nothing about Cobras. I'm primarily an AGA-T2 man with a ZAP to boot ... :)
But then I'm not overly interested in hardware beyond the scope that it does the trick, and that's first and foremost in your wick & coil setup.

With these wicks, the vapor is so voluminous that I bored all my genny's cap airholes out to 1/16 to match that of the ZAP. Way better vape.

The Cobra's wick hole is 2.5mm. 3/32 is ~2.4mm so the 3/32 would just barely fit (a slight gap is welcome for wicking from what I hear). The 7/64 is ~2.8mm so it would take some sanding to get it to fit. I could technically widen the hole a little but everyone seems to agree that 3/32 seems to be the best wick size ATM (due to heatsink affect or something, not sure what the consensus was).

Not sure what the wick hole size is on the Z-Atty. If it was 3/32 you'd think they would start making FC-2000 for that size again (although since they're releasing a new "version", even if it was 3/32 they might enlarge the hole to 7/64, who knows).

I drilled out my AGA-T to 1/8" so I can use the 7/64" wick. I haven't seen the Cobra but if it can be drilled to 1/8", which I'm guessing it can unless tolerance is really tight, I'd recommend doing that. It's going to be less hassle in the end rather than sanding down wick after wick. I get about the same wiggle room with a 7/64 wick and 1/8 hole as I did with a 3/32 wick and original hole. It's also a little more durable, I don't feel like it's going to snap if I look at it wrong...not that it ever did with the 3/32 but I always was very careful and felt that way.

I thought I'd prefer the 3/32 also due to what people were saying about the heatsink effect but it's really not that much bigger and I don't notice it much if any, the 1/8 might be more effected. I also found the newer 7/64" to wick better, not sure what they did if anything with the last run or if its due to more material but it does seem wick better. Keeping it completely vertical and everything else the same as much as possible I tried a little test coiling a dry 3/32 and filling the tank 1/2 way, after pulsing I got some wisps and vapor but nothing to write home about, did the same thing with the 7/64 and got much more vapor in less time. It does seem like an improvement to me so far.

I drilled out the cobra clone and if its anything in size the same as the cobra then there will be no room what so ever, heck the 1/8th hole I made is actually through the edge of the top part of the housing where the center post is, about 5 - 7 pages back I think is where I have some photo's, I must admit I did drill it out by pushing the atty around while the drill press was running the bit so it can bore it out a touch so the 1/8th wick is very free in it.

Just another vote for the 1/8 inch wicks here. After making a couple of mega-wicks of various configurations with my RSST (5mm+ wick hole), I've put the bushing back in & I'm now running a 1/8 inch ceramic again. Even with the bushing back in - the wick hole is still around 3.5 mm, so a 1/8 inch wick is nice and loose,. It wicks very well, even without a grooved ceramic.

I took a well-used 1/8 fishstick out of my drilled-out AGA-T2 , torched it clean, used the cheesecloth thread method (no hot-wrap) set it up with .5X.1 Ribbon Kanthal.....wrapped it nice and tight right on the atty.

No break-in at all - great flavor right away, and very fast heat-up. I think this might be my preferred method to set these up now, much easier than the Hot-wrap (not more burnt fingers!!), and NO break-in time! I plan on making a new slotted wick for the AGA soon and give that a try with the cheesecloth wrap method also just to see how it will work.

I liked the larger wicks for many reasons. They are very robust, and great flavors, but they take a long time to heat up. Once they come up to temp, they work well, but unless you can keep the wick hot (chain-vaping), or don't mind hitting the go-switch and waiting for about two-three seconds to take a toot, they are a bit frustrating. The RSST with the loose-fitting 1/8 ceramic & cotton-wrapped Ribbon coil is just outstanding - the best its ever been.
I tried the 3/32 wicks a couple of times, but I was never successful in getting one to the point of being able to actually try one. Out of at least half-a dozen I tried making or wrapping - I broke every single one before I could ever give them a decent try. Just too fragile for me....

When the RSSTs become available again, I plan on picking up at least one more to try experimenting with a slotted mega-wick - that might be the answer to the vape-lag problem - eliminating some of the mass of the wick by cutting slots in it might be the solution. Right now though, I just want to enjoy it as-is.

Biggest thing I've taken away though is how well the thread of cotton under the coil works. Thanks for the guys who recommended it....I'm impressed.

My AGA is also bored out to around 3.5mm as well with the 1/8th wick, yes initial vape takes a little longer, but one thing I found is that if it is snug then what appears to happen is the heat is transfered into the head of the atty, but when it is loose the wick alone gets hot faster.

Im waiting on my RSST, hopefully with the same results as your getting so I am reading with interest indeed.

I need to find an RBA that is no larger than 5/8" in diameter and has a clear tank for my PV. I don't like to carry around these large PV's. Has anyone found one that can be drilled out to 1/8" made of stainless steel? I keep looking at the AGA-S but it only comes with the stainless tank.

Yep - there's a guy here in Florida who sells a Cobra clone in Stainless steel. I believe its about 5/8" in diameter. I don't have one myself , but I've been in his shop & I saw it first hand and it looks pretty good...price its right also. I don't really know if it can be drilled out to 1/8 easily though... If you have questions about it - give him a call or send him an email - seemed like a nice guy and ready to help.

I was out there for Bike Week & only had time to look around for a few minutes, but I'll probably pick one up the next time I'm in that area.

I called them and they are not 100% sure that its all SS, but he thinks it is. It is a little bit larger too. I can't decide yet. Thanks for your help.

the 3/32 wicks are the older version , with the 7/64 they changed the porosity for better performance, they were unable to do this with the 3/32 wicks so they discontinued them, so I am not surprised that your getting better results with the 7/64 compared to the 3/32. personally I haven't tried the 7/64 size yet, but have some on the way. with the older composition wicks I seemed to prefer the 3/32 over the 1/8 size, but the newer 1/8 seems to be closer in performance although I do have one 3/32 wick that just seems to be special. I have set-up a few different 3/32 wicks and have found them on par to the 1/8 wicks, but this one particular 3/32 wick is just superior. these wicks can change from wick to wick in their make ups, their just like a bunch of little tiny rocks put together, so each one is a little different.

besides the problem of maybe not having the room to be bored out, which I am not sure of, the cobra may be a little harder then most to bore out because they are titanium. I have not heard of anyone attempting this on a cobra.

if you are looking at the aga-s, then I am sure you can get one with a glass tank for it. I bought a glass tank for my aga from ibtanked, fits perfect and ran about 10-bucks

I was using my omega mod with my ac-9 yesterday, as I was driving home and listening to some music, I found myself tapping my mod on my knee in beat to the sounds. when I got home I started to realize that I wasn't getting a good vape, opened it up and the darn wick had broke. instead of putting in another 1/8 wick, I installed a 3/32 wick into the other wick hole(theres 2 wick holes,& 1-fill hole in the ac-9) which is kind of far from the neg screw, but its working great.

Hope that was not your favorite little ripper 3/32" mate . . . no more nick knack paddy-wack for you on the way home :).

If it is the cobra clone that I have then it's like a brass material, it flakes when drilling it exactly like brass does (I drilled through it) but the cap is stainless. About the only thing I like about the whole atty is the center post, nothing else is nice, even the clear "plastic" tank is warped in moulding, the outside is smooth but the inside is bulged on one side almost like they rolled it up when it was hot to join it...
