I brought one recently...the one with the index finger...so far very good...no more breaking of wrist at the release. Sorry can't compare as I didn't get to try the other model.
BionicBowler,
One question for you...do you always change the cupping position during games or league to throw the spare ball ? After constant changing of position, will the locking mechanism (screw) come loose or last ? That is my only worry...
