I'd throw 2 cents in the ring and say, skip the shaky cruise prop and put the Borer back on. The speed difference isn't worth the aggravation. (nor the higher fuel burn)
There's a 160 hp modded up 12 here that once sported a 76/58 (going to AK and back) cruise prop. It was a no good, wretched, awful, inefficient, beat-the-air-to-a-froth-without-going-anywhere, lousy combination. :-?
(I would assume a 56 would be quite a bit more efficient). Finally the owner was convinced to put back on the 82/44 Borer that came with the airplane when he originally bought it... aaahhhhh...WHEW! mucho' bettero' all around. 8)
Also, ditto Speedo's post res 1-40 etc...
