Mirage vs Laser on a 20 SF

[Blue_Heron]

I'm looking for the difference in WOT rpm for a Laser vs a Mirage prop of the same pitch. Has anybody here run both props on the same motor/hull and can tell me if there's any difference?

I've heard that the Laser is a better choice than Mirage for a 20 SF. I'm currently turning a 14 1/4 x 21P Mirage with a Merc 200 carb motor. It turns about 5200 at WOT. I want to try a Laser and get the RPMs up to about 5600-5800 at WOT. I'm thinking I'll need to go to a 19P to get the RPMs up, but I don't want to get them too high.

Thanks for any input,
Dave
