Re: 6 Blade Props?
I believe this one is a 21", so pretty steep for small stuff. In the area where Hill is popular, mostly V8s with Alphas and Bravos, although he is an OB, Mod VP type racer guy and doesn't use these. He offers a lot of racing props too.
I don't think I would run one as I am looking more for top speed and efficiency (just 'cuz) than hole shot. In fact I am finding hole shot to be less and less important as I pull tubers and wake boarders and don't need much to get them up compared to skiers. Although launching up and out is still fun 8)
BTW, I say "just cuz", because I can't see how prop efficiency could save me more than $2 a day unless it was waaaaaay off to begin with . . .
