Well ok as far as building goes I started by rebuilding coils for my pro-
tanks, I use 32 ga a-1 kanthol with 3mm silica for that. That's what I started with, and my builds are around a 2.0 to 2.5 ohm coils, which is a good range for the provari. As far as taste goes they are very simular for my kayfun, and my dripper, I can't say that one is better then the other. I tried using the silica first, in my kayfun, and I had a hard time getting flavor with silica, (I don't know why) I kind of want to try the silica again, but
I switched to using cotton, and the taste is great, but changing the cotton wick is not easy, I destroyed a coil today trying to do that. I have not tried the micro thing yet, but if I did I would try doing a dual coil configuration so my over all ohms is not to low. I did a 7 wrap on a 1/16" wire today and ended up with a 2.5 coil, and I have my volts at 4 right now.
One thing I would like to add is the Kayfun lite, really creates a cloud of vaper, I was driving with it the other day, and I almost couldn't see the windshield.
