I know there are several IBTanked fans among the Provari users. I just got my first one a few weeks ago. Bought an XL with a few 2.0Ω cartos. Getting ready to order a few more tanks but looking for some feedback. Which resistance do most of you prefer?? the 2.0Ω or 3.2Ω?? I know you can use a wider range of voltage with the 3.2Ω. But do you give up anything using the higher resistance??? or is there really no difference.
