i dont know.... he just kinda stalls a little when he lets go of the grab, to be a legit shifty, you gotta really shifty in the opposite direction. i guess you can call it a shifty, its alot easier to say then mid air stall. its still sick, but this guy wants legit a legit shifty.
for a big spin shifty, i think bibby's and nyman's are the best. though its hard as hell to do them with big spins.
