I have the XB21 Pro Elite with a 250 1.62 sporty. I run a 28 Bravo1 worked by Robbie. I have dual 8' PP's and can run 83+ with two people loaded for tournaments with full livewells. The hole shot is a bit sluggish but once on pad it gets some gone. Running solo the holeshot is a non issue. If doing short runs I would go with the smaller prop. If you are running any distance at all I would opt for the larger prop.
