So, I know on a lot of RBA/RDA people leave the wick long and stuff it onto the deck. Since I've been using mine I haven't seen a reason for it because the wick next to the coil drys out and gives off the funky silica taste before it wicks the juice from the rest of it. Is there something I'm missing or is it to gather the "over drip" so it doesn't leak?
I don't understand it either. The wick will always be uniformly saturated (or dry), and there isn't some unknown force that makes more juice go to the coil than anywhere else in the wick. Once it gets below its holding capacity overall, vapor will start being reduced. The more wick you have stuffed in, the more juice will basically be trapped by it and it won't be vaporized. Long or short, it needs to be kept saturated. I can see having a lot of wick to prevent leaking, but I would think that a short wick is more efficient in terms of using all the juice you put in. Of course, you literally have an uncontained pool of juice in there with a short wick, which can leak, but it will tend to be gathered around any part of the wick touching the deck.
You can reduce the funky taste by using a thicker wick (folding over more times), by letting both ends coming out of the coil touch the deck, and by making sure the coil isn't wrapped too tight. It should only squeeze the wick slightly.
Cotton is a better wicking material but it burns pretty easily of you aren't diligent about keeping it saturated at all times.
