Friend owns a 2016 Z21 with 250 Pro XS, he is running three blade currently. He is debating a 4-blade again, ran a Bravo I XS on his Z9 before. Anyone tried the Fury4 or the Bravo I XS on this boat yet? He is wanting better holeshot and best speed can get for 4-blade. Any information that I can relay would be awesome, thank you
