Well the isub was really meant for sub ohming you could try temp control if you want the sub ohm clouds without a lot of heat as you can go down to 200F on the temp also you could try a air control drip tip it would cool the vapor down a bit i dont have hot vapor on my istick tc40 in wattage mode at 33 watts on my isub so it could also be the juice you are using i guess or close off the air flow a bit to the isub and do very short hits i have my isub open all the way and the vapor is nice and cool just giving some options hope some of them work that is if you are looking for big clouds
