Im wondering what would be a good 22 gauge build for clouds on a sigelei 150. Using my sig 150 and troll rda. I have tried 8 wraps 2.5 mm and 7 wraps 3 mm. Have'nt decided if I like 3 mm or 2.5 mm inner diameter better. I think I like 3 mm better as it wicks better. I know surface area is better for clouds.
