If you really want the Oh S***! performance factor, the 2.85 is the right way to go. I'm still willing to sell you my old prop but you can skip that step if you want. Seems like a lot of expense for a short term improvement in top speed. The Warp Drive prop will probably equal the Performance Prop on takeoff performance. Spend that money of the new engine mount!
I also agree with everyone else that the reduction in engine life is not a big real world factor with the 2.85 drive. Still will be well below the threshold of catastrophic failure modes and I doubt that I'll ever wear a rotary engine out in this life time.

Greetings,
After yesterday's measurements, and a night of thinking about it, I'm going ahead with the -C drive and 74" prop. I haven't exactly decided how I'll handle the left offset that's in the mount, but where there's a will, there's a way. The drive order has been confirmed by the nice lady at RWS, and I'll pull off the Warp prop later today to double check the hub measurements for my Performance Props order tomorrow. Due to the lead time for the drive and prop, I'll spend the Summer flying with Tracy's old prop, and trying to settle on a final intake.
Cheers,
Rusty (not exactly getting an early start to the airport...as usual)
