Hmm right now, I'm using silica, about 5 wraps with 28kg. I'm getting a "dry" hit, almost like I'm breathing in a light powder chalk. I prefer heavy, wetter hits, if that makes any sense. The flavors don't seem to be coming out quite as strong, I will try to take pictures once I get home. I do have some bamboo I purchased earlier, but I'm yet to try it. I also use a hex wrench, wrap the coil around it, and pull my 2.5mm silica through, and it the wick seems almost loose and not touching all the sides. Could that be the issue?
Well, this is what Robert posted about his set-up:

For Grand
28 gauge wire
2.5 wick doubled
5 coils
it will rip your lungs out!
Seems that will give you a very different hit because of the low ohms. Might be very tough to keep wet. And will probably mute flavor.
