I built dual coil cotton wick on my trident clone and the vapor so far is not nearly as much as when I used silica. I am about 2 hours into the new build and not much improvement. I also want to know how big the wick should be. Thanks in advance for your replys!

Pics, please - they really help.
Sounds like you've got a wicking issue, specifically too much cotton.
The rule of thumb is to only enough so that it freely passes through the coil (assuming you're wicking through it), and keep the ends short (maybe a quarter inch beyond the coils on either end).
Pics, however, would help us dial in some recommendations.

The amount of cotton is critical. It's a cliche and I've heard it over and over, but less truly is more in this case. As far as length of the cotton beyond the ends of the coil, I personally cut one end close to the coil and leave a tail on the other end just long enough to wick up any juice that finds its way to the deck - in other words the wick is long enough to touch the deck on one end. Works for me.
I would dial in a single coil before going dual.
My 0.055" coil likes a barely snug cotton wick.
My 3/32" coil likes a medium snug wick because my larger wicks tend to collapse.
Wish there was a more scientific way to describe wick in coil snugness.

I'm fairly opinionated on my cotton wick, I've read MANY posts about cotton and this guy has always been spot on from my experience. The thickness of cotton to use is finicky at first. I also agree with another post saying fine tune a single coil first. For a single coil: *disclaimer, I do not go for sub-ohm just a simple quality vape*. I leave about 1/4 inch on one end and 3/4 inch or a tad less on the other. Cotton goes through my coil, short tail I lay back on top of the coil, large tail I'll snake around the base to catch excess liquid. I'm certain there is a "better build" but for my 1.4-1.6 ohm this gives me a consistent winner so far. Last tip, and prob the best, my trick for correct thickness of cotton: pull a pinch off as I use org cotton balls. I'll stretch one end out more so but remember to work the middle a tad until I have a cone shape. Small end goes in easily and I'll pull along until it's about to fight the coil. Back it off just a tad. The small end I used to start the wick is the small tail I mentioned and lay on top.
It is really difficult to describe the proper way to wick with cotton, as everyone's idea of loose and tight seems to vary somewhat
The best way I found to describe the proper tightness, is to sit your pv on a flat surface standing up, and pull the dry cotton side to side. If the cotton moves inside the coil without disturbing the pv, it's loose enough. If the device moves or shakes at all it's too tight.
You just have to do the goldilocks method till it's just right. Density through the coil is the key, everything else is just personal preference and atomizer restraints. I generally twist up a strand tightly so the it pulls fairly easy through the coil with little resistance, then untwist it to fluff up inside the coil.
It depends on the RDA. Some RDAs set up with the coil higher off the deck than others. The critical thing is to have the coil even, or slightly above the air inlets; never lower than the inlets. After I mount my coil, I set the top cap next to it, on the outside, and move it to where I want it, in relation to the holes. If it's a device where the coil sits high, such as the Helios, I'll leave the tail of the cotton long enough so that I can double it back onto the deck, under the coil. If it's a device where the coil wants to sit low, I'll just leave enough cotton to lay on the deck.
I agree on everything above
what I found is if you have to much wick inside your coil it will taste the same from the time you start vaping that wick till the time just before it runs dry of juice, it'll be tight. But if you've wicked it correctly I found that right before it runs dry the vapour increases, yeah I know it sounds funny but go test it its like when you overflood you get hardly any response but as it drys ..
I will also run tails from either side of the coil the same thickness as the cotton inside the coil and not any thicker, and just run one down by the front of the coil and one around the back making a s shape
i prefer single in trident, i wish i could take a pic for you but i broke the terminals so its in the garbage now, dam clone lol

ok so with all this cotton bed i have been hearing about lately... if the cotton gets too dry in one are does it burn the cotton? i would kind of like to play with a cotton bed... but want some more info on it first
you will know when it needs more juice, the juice in the cotton will wick to the dry spots . if it does burn just take it out, dry burn, new cotton, juice it and go! on my IGO-L my cotton bed is about 1/2 the deck size very small pice of cotton. thats why I like cotton bed just so E-Z
never burned a cotton bed in 5 months, or ever

i will have to toy with it sometime... gotta get my nano coil set up tomorrow first
trust me i know that i havent rebuilt my coil since i slapped it in... over a month ago...
Great advice so far. I see one problem in the pic that wasn't mentioned. Airflow is key in either single or dual coil configurations and one of the coils looks like it might be a bit restricted. You might want to make sure you have a direct path (no cotton in the way) from the airhole to your cotton. Also, maybe this is common sense (it wasn't for me), but your cap's holes should be lined up directly with the coil or you'll get dismal performance. As others mentioned...the amount of cotton is also key. I was overloading my cotton, too...but one time I tried a bit less and it was like night and day. You'll get the hang of it...but less is usually more.
One other thing to remember is that you might not be able to get those monster clouds you see on the videos, so you probably shouldn't expect that. From what I can tell, most of those are from particular juices. Sure, build quality has a lot to do with it, but cloud chasing is kind of silly in my opinion.

I've tried this, but I can't make it work for the life of me.
Could you post a pic for the dim-wits in the audience?
Speaking of cotton wick ... I have a question:
Some of these 'micro-coil' builds that are now being made on thin needles have coils with such a small inside diameter that only a very narrow piece of cotton can be used ... just because the hole is so small in the micro-coil.
Do you think that this may be causing some problems with wicking enough juice into the coil?
I am just saying that you can make these coils so small in diameter, you just can't hardly get any wick material in them, which don't seem like a very good idea.
