Only other thing I recommend if you want vw is get a kick and tube mod. Honestly, I don't quite understand the need for a vv and vw combined since you either use one or the other. I recently got the BAM with a 26500 batt and kick and it's amazing! I also have Provari's, and bottom feeders. If you really want a vw bottom feeder, there are some that you can probably Kick. In that case there really wouldn't be a need for it to be vv, that I know of, because you can't use vw while using vv.
