If your running the factory 4 blade on your SX, you can switch to an acme 3 blade and clean up the wash atleast 50%. I was VERY suprised how much cleaner my wake is with the acme. Only down falls I can see in switching rotation is the gears have taken a set to a left hand prop and you (could) not saying you will , have some gear lash issues that could have some bad results at some point. Oh yeah there is not as many options for RH props as apposed to LH props. On my old E22 I wanted a wakeboard only prop that acme suggested and they did not offer it in RH rotation.
just my .02
