Has anybody modded the k101? I want to enlarge the air holes but dont want to do it unless somebody else has and if it improves performance with lets say a protank with rebuilt head on it. It works fine with my rda on it because I drilled 2 larger holes in the rda. But for things like the pro tank and vivi nova I think larger air holes in the mod will hopefully make a difference maybe maybe not. Or if there is other mods you can do with the k101 if like to know! Thanks yall
