not sure; the Bulli may be small for all i know... there are some small profile gen mods coming out now that would fit the infinity fine... like the Gen Line... the bulli might be the same.. the infinity isn't much bigger than a ego i think and there are some photos out there of the bulli on pv's... like the ego, and comparing it in size to the Mark T, which is made for an ego more or less; you might be fine with the Bulli...check it out.
appreciate the advice ukeman,
its the non tank bulli i was thinking, still too top heavy do you think for the infinity?
also i would predominately be using carto's
really got my heart set on the infinity over the buzz, wanting to click the card through as soon as, but don't want to make an expensive mistake.
