Last I know Ivo still has their 30 day money back return if you're not satisfied. Maybe give them a call for advice?
My 68 inch prop on my kitfox is faster than the 72 inch I tried, and my cut down 66 inch is the fastest of the bunch, but my climb was reduced by about 25 percent compared to the 72. So my 68 is a good blend of cruise and climb.
So... maybe Daryl at Warp would let you try some shorter blades?

Re: Which Prop
I'd love to know how the new Catto and Prince props perform in the (required by Rotax) Mass Moment of Inertia test. A 72" tapered tip nickel Warp Drive will fail, leading to premature gearbox wear and damage.

Re: Which Prop
I believe the 70in 3-blade Warp is as much inertia as the 912uls can handle. I believe someone did a test on it. Not me...

Re: Which Prop
I tested my 70", taper tip, nickel inlaid, 3-blade and it was okay. It is right at the extreme limit, but it was still okay. I have had to do gearbox repairs at 400 hours TT on this setup...
I was hoping that the lighter weight and two blades, rather than three, would offset the length of the Catto/Prince options.
