Lower bb stocks do generally feel a bit nicer, I think the wheels are a bit too big to try and feel really flicky on the back wheel. I don't ride stock though.
Mods feel pretty awesome with a high bb, as they're tiny and just backhop and sidehop anyway, so why not make doing those as easy as possible, by having a +70 or more bb height. 24"s are the same, still feel flickier than a stock but more stable than a mod.
