I recently got an istick 30w, and the thing's awesome. However, I was wondering what the best wattage range is for 0.5 ohms? Im using an ego one atty, which is supposed to be 0.5 but reads 0.4 ohms. Just looking for a ballpark, from there ill fiddle around to fine tune which i like best taste and vapor-wise. I know i cant be the only one to pop an ego one atty or something similar on a vw battery, what do you guys find works best? Thanks
