I will try your suggestions out. The spaced coil with wick in it I posted above, is working well though. Not had a dry hit with it. Maybe, just maybe a little less flavor? But I'm not sure if this is really the case or that it's placebo effect from reading about muted flavor with spaced coils. The contact coils I used before were not damaged I think. But it is possible. Maybe i'm dry firing it too much and scraping it to get an even glow. It's a 2.5 ID btw. I do get the sizzle sound wich you mention. Will try even more cotton, although I'm using so much already that its almost impossible to pull it through. I did see that the juice i'm using now, does contain sweetener. Something my previous juices didn't have. Maybe its creating a build up of carbonized sugar or something.

I do stuff it full and don't leave space to the sides of the wick, but I do make the wick really 'airy'. I rake at least 50 percent of of it before stuffing it into the well. I will follow your recommendations on this.
It would be interesting to see a picture of the way you guys build and wick. mainly for the amount of cotton used. Thanks again for all the suggestions. This is a great forum.
Good luck. I don't fan it out cuz it just lends itself to blocking the juice flow holes in the deck. Next time you have your deck out, look in the well. You will see two small juice holes on the floor of the wick wells. Those holes are spread apart up next to the sides. Try and get your wick to the inside of these holes (may necessitate trimming the width of your wick tails...that's OK). When you take a puff you will be sucking juice into the well that your wick will sop up. So you don't want to block those juice holes.
The amount of cotton inside your coil can be pretty tight. In fact, better tight than loose (too loose and you'll get dry hits and lots of popping). But the wick tails need to be groomed according to what I have stated earlier.
Well your diameter is good and at 2.5, your tails shouldn't be so thick as to choke your channels. Next you may want to try slightly reducing just your tails about 10 percent by trimming the 2 sides and bottom. Just don't trim all the way to coil, try stopping the trim 2mm away..I always have better wicking when my coil was a bit shorter and allows me a puffier wick shoulder rather then a straight consistent wick dimension from coil all the way down. Also the lenght, you just barely want them to touch the bottom. When you pull cotton thru on your 28g coil, do you have to hold the coil with fingernail to prevent it from moving? As you said, it could be your juice as well because a gunked coil can taste like a dry coil and some juices just gunk faster for sure...I vape net juices and probably get 10 to15 mls before changing wick...if coil and wick are optimal, it should only require one 1 to 1.5 on juice control. I'm running a .6 to .9 ohm 26g build at 23 watts and have no issues chain vaping (just for tests as I normally don't chain vape) at 1.5 turns. That sizzle sound is common to all builds, but it should cease in a split second after, if you release fire button and immediately bring the tank to your ear, it should cease pretty much 1 second after. If you feel it continues a bit longer you may be able to add a bit more...whenever I have had dry hits from not enough in coil, that sound kind of gets a bit longer and more noticeable. ..

I use rayon, so it's slightly different. I pack a bit more in coil and trim 20 percent off my tails as seen in the video on the first page in this thread, but tbh it's not much different to how I wick my cotton builds...if you look at the video , you can very well do the same with cotton

Is there a particular reason you use contact coils instead of spaced ones? I seem to see a lot of youtube reviewers using spaced coils. Also for me personally I think its easier
Yes I have to hold it with my fingernail to not destroy the coil when inserting the wick. Is there a particular reason you use contact coils instead of spaced ones? I seem to see a lot of youtube reviewers using spaced coils. Also for me personally I think its easier because of it glows even from the first time.
If your holding coil fairly good as to not destroy, your probably using a sufficient amount. How about when pulling out the old cotton wick? Does it just slide out easily? Or is there a decent resistance? As for contact vs spaced, I don't use one more then the other actually, sometimes I use contact, sometimes not, just depends on my mood I guess. I honestly don't see a difference in performance or flavor, but it could just be me in that I can rarely tell differences in lots of things. I often hear people say they love cotton and hate rayon, or that they love a 1.8 ohm coil and don't like a 1.2 ohm coil. I can only detect very slight differences in those examples, especially the cotton aspects. To me, most every type of cotton I have ever tried all were very close in which I did or didn't notice much either way. I really don't even notice a big difference in my builds, I have about 4 rta's set up with 26g, .7ish ohms and 4 set up with 28g, 1.3ish ohms, both over 20 watts and they both are very close imo, so maybe it's just me....maybe the difference comes at higher wattages, as I can possibly see better wicking with a spaced coil at wattages over 30 or so?

I actually just had to rewick my prime, so did a cotton build. As I don't use cotton all that much, all I know it's ... cotton that I got years ago, so not sure if it's muji, ko gen do, etc. I know it's a 3x2 inch pad that's measures about 8 or 9 mm thick. My coils ID actually measures 2.42 mm and the width of cotton used measured 7mm wide without peeling off any top or bottom layers. I threaded thru and definitely had to reduce tail amounts as you can see. Once completely done, it looks perhaps as theres to much in channels, but because I reduced tails, it only appears to be. The trim was cut short of coil edge, which gives the shoulders a full look.

Nope...same thing I guess about my tastes, sometimes I do and sometimes not and I can't seem to tell the difference. ..I think most of the time I do however, but because I wanted to give a specific measurement, I left it on...I did mention in the post that I left it on just for comparison

I know there are many ways to successfully build the prime and each probably works different maybe because of each ones vaping style. I know my specific way isn't the best or even work for some, but it does work great with my juice, wattages, and draw....I just wanted to show another way, just incase another's might not be...I sometimes think just seeing one little detail can possibly help.. and I agree, you very might have a touch less cotton in your build, and if so, no need to trim....I think the trim really plays a bigger part when coil I'd ' s are bigger

Again, if you twist the wick tightly as you feed it thru the coil it will slide in easily. Once through, you can untwist the wick.
Sometimes I think that maybe I need a touch more cotton in my coils because im vaping mostly at 23 watts...maybe at first, the power I run breaks in the wick, whereas maybe if someone is only vaping at 10 watts, it doesn't and a thinner piece is better..and because my wick is thicker, It requires a thinner tail ? Just too many variables that just takes too much time to nail down all possible ways....but maybe the baseline of approximately 7mm in width of ... cotton in a 2.5mm coil kind of gets one close....but even that has probably variables? I'm sure each type of ... cotton is different in density or perhaps thickness.....

I, on the other hand...
Run about 7.5 mm peeled Ko Gen Do cotton in a 2.5 mm contact Kanthal coil measuring 1.9 ohms at 12.4 watts
I could not imagine changing anything.
And I chain vape it... Like I Stole It!!!

So the measurements are pretty much the same? A 7.5 mm strip might be pretty darn close to 7mm without peeling

I had the Kayfun Mini V3 but didn't buy the 5. I was a little on the fence about this atty. I had a Berserker which had good flavor but kept getting spit back and the Siren V2 was a huge bust for me. I ordered the Prime last week and it showed up on the 23rd a day after my birthday. Finally got to wick it tonight and did a nice space coil at 1.50 Ohms. So far best $119 I have spent. Don't know why so many people think the V2 Siren or Berserker are close to the Prime. It's really no contest. The Prime is the best MTL RTA I own right now. It was super easy to build and wick. Just trying to decide if I should get the entension tank right now. I lost one of the screws in the floor so already gonna order a spare kit. That little bag ripped on me a little when I opened it 
Only thing I didn't like was my tank was a little loose in the packaging. The paper had a little tear and wasn't snug so it rolled around a bit.
