I tried 28 gauge and that's all I use now
infact I ordered 100 ft x2 worth of kanthal 28 g
lightning vapes thru amazon like 7 bucks per 100 ft roll.... just find it easier to work with.... I have tried 30g and 32g and had difficulty coz it's too thin for me.... also I liked having to make more wraps for a lower ohm resistance....
