I'm amazed at the replies here that say the Super Trooper snaps.
This ball has no flip blocks!
It should hook but not snap except on flying backends.
Oh, as far as Ti Messenger Pearl vs Ego, I think there is no comparison, you want snap and energy retention EGO is all that and then some!
A great high octane ball with a great coverstock(UFD, what is this explosive stuff), and a great core(reaction rev).
