Another thing I've noticed about it. is that using it with the stock steel cap, isn't as good as using a polished pmma cap. i can actually see how saturated my wick is, and i never ever over or under squonk, since i can see whats going on in the atty. as a side effect my wicks last way, way longer. I might be bias, but i also think i get better flavour with the polished pmma cap. I think when i order my next hadaly, i'm going to order 2 of those pmma caps that you can put normal 510 driptips (mmmm hippy multicoloured resin) in. Because the intergrated one i have is a little short, and the bore was a little too tight for my liking.
