I tested nine different FP props on my RV4 over a 10 year period. I always went for the "big 5" first then the finer points that separate the average from the good and excellent. Mission requirements always override perfection and going in a FP will always be a compromise. A lot depends on your requirements and mission.
That said...for my requirements I needed off pavement capabilities, high altitude cruise and rain protection. This is what I found on my short gear RV4, 2 blade test.
1. Ground clearance: 69" optimum.
2. Static RPM: 2200
3. WOT at SL: 2750-2800 5000' 2700 (24"/2400 match), 10K 2600- 2700
5. Cost, durability.
Winners: Catto Gen 2 (I helped Craig develop his props for RVs, great guy)
MT 2 blade FP (incredible German engineering and quality)
Gary Hertzler 2 (unbelievable performance and high tech airfoil)
Contender I tested on a 9A for Sensenich, the 2 blade GA composite. Amazing prop.
Testing requires a lot of hours at different altitudes, seasons and aircraft weights.
Bottom line, it depends on what you want, or what you need...there's a lot of info on this site, search threads and you'll see a lot of data.
