I got some in the mail from HHV as we speak. Should be here this weekend or Monday. I'll see how they work and post up on it.
I keep hearing about people putting cotton wicks on novas and nother rebuilable type
tanks/clearos. If cotton is so much better, why aren't manufactorers making units with cotton? I guess you can't dry burn the cotton, but I've never had much luck with that. Dry burning seems to turn the wick under the coil black.... seems like after its turned dark it always has a hint of that burnt taste.
When I dry burn, I only do 3 second blasts (when the wick is still a little wet from cleaning) until I can see the coil glow wile looking down the center. As soon as it glows I stop, but that still seams to turn the wick that brownish burnt color.
