I have alpha 2's
Pros: fun to butter, makes them less useless in pow.
Cons: take a while getting used to on hardpack (turn weird)
I know just from jumping stuff with my ARG's, rocker has less pop (obviously) and requires a bit more work for a solid take off. So get ready for quite a few straight airs to get the pop and takeoff right.
Spinning is fun on em though!
