Another +1 for the Catto 3 blade on an RV7 IO-360 EFII.
Initially I went with the "good all around prop" that Nicole and the website recommended and found quickly that the pitch was too small. It climbed like a homesick angel. At WOT it would overspeed the prop down low easily and wasn't getting the TAS up high. NIcole then recommended adding another 2" of pitch. This brought the initial climb down about 400 fpm (? maybe) but allowed a much higher cruise speed.
The final prop is 64x78” and it will top out around 175+ IAS at SL (2700 rpm), still climbs great at SL, and will show 170 - 175 TAS at altitude fully loaded (10-13K') on about 8.5 GPH LOP. The airframe is pretty slick and medium weight, and still screams in the climb with just one pilot on board.
I've noticed that as this prop is accelerating from low speed you can really feel the prop pulses until it "gets up on the step" and then it smooths out and really takes off, probably due to the aggressive pitch. Overall a pretty good compromise IMO.
So if you have questions, talk it over with Nicole. She can take care of your issue and has great access to some other pretty smart prop people in the shop too.
Cheers
