While my build is working fine, i was just wondering about what to do with the wicking... Do builds work worse when over wicked?
Problems with over wicking?

Using too much or too little wick can certainly affect the quality of your vape.
Too little wick can lead to dry or burnt hits, as not enough liquid is reaching the coil to prevent burning.
Too much wick can cause strangulation of the wick and e-liquid, leading again to dry or burnt hits, or the opposite being a flooded coil.

I don't think that qualifies as "over-wicking"... perhaps it just appears that way because your coils have such a large ID. I suppose that, in theory, over-wicking would take longer for the coil to reach a vaporizing temperature, as the possible over-abundance of juice would act as a heat transfer medium.
What is your net resistance, and what type (Kanthal A-1?) and gauge of wire are you using? Perhaps your heat flux is too low.
Too much wick also greatly limits the airflow.... which I suppose isn't a huge deal if you are using a tank with low power. But, if its an RDA and you are pushing a ton of watts at it, your wick is going to restrict your vapor and allow the coils to get hotter than they need to be.
I've found that it's better to go under than over.
One person once said that a good way to test is to thread your wick through the coil, and if you can topple your mod by pulling the wick (ie: there's enough resistance from the wick being thick) then you probably have too much cotton. I like to ensure that there's enough cotton to amply fill the inner diameter of the coil, but not so much that I'm noticing dry hits while there's still juice left over on the cotton (you'll be able to visibly see juice, yet you'll be getting dry hits, this is usually because the juice isn't flowing freely through the wick).
So a "less is more" kind of mentality seems to work best. YMMV.
Is there a good general rule of thumb to help determine how much wicking material is just right?

Never mind - just saw the post above. Thanks for the info!

Considering the potential variables in the builds of just this one thread... it's still all rather subjective.
Loose density and only very slight drag in-coil... which still adds up to "less is more". ;-)
Depends on what you're using as a wicking material.
With Japanese cotton I've found that a good general rule of thumb is to use just enough that it's a little snug going through the coil, and then once you have it centered gently tug it back and forth a little until the center of the wick can move smoothly through the coil. That helps keep it from being overwicked through the coil once it's filled with juice.
For me I've had more problems from not enough wick in the coil or wrong position.
Snug in the coil works for me.

I lean towards the Less is More opinion. Wicking is just one of those things that You have to play around with and figure out. And it seems each build is different, in regards to wicking. So play around and find what works for You! A giant bag of cotton balls is like $0.98 at Wal-Mart.
