Randy,

I talked to Daryl at Warp Drive on the phone, and he said that I might get better Soob cruise with a 3-blade 68" prop and about same takeoff as the 72". He said you have to flatten out the 72 prop too much to make static rpm. I ended up with a used 70" anyway. Wish I had the tapered blades. Guess you got the best of both with your IFA IVO.

Someone else on here stated that they had the same results, (better cruise, same TO), with shorter prop and more pitch.

Of course, we are talking about 3-blade performance, not a smaller 2-blade - usually 2-blade props are larger diameter than the 3-blade for the same engine.
