I actually like 28ga at around 1.6-1.8Ω for a KFL or clone. Lately, I've been playing with a macro coil... 7 (tight) wraps of 28 around a almost 3mm shaft. Doesn't get too hot even with long hits, good - not great vapor... but, the most important thing to me, as I'm not playing in a "cloud contest"... a very good, clean taste.I have some 28ga on its way. Ordered it from Lightning Vapes - All the RBA Materials you need! Silica Wick, Ekowool, Kanthal Wire, Stainless Steel Mesh and more! Going from 30 ga to 28 ga should bring me from 1.8 ohms to about 1.2 ohms all other things equal.
Not saying it's your cup of tea and I certainly don't suggest it's the best and brightest... but there are more ways to skin a cat than with just one kind of coil. ;-)
