Your best bet would be to lab the 23's get the rpms up to where they need to be add some cup to them to carry the bow, your cruise and WOT speeds should both pick up some mph..

The plan would be to take a lil pitch out.. to 24ish " and lab to get some more rpms.. since I own the 25s.. would be cheaper.. I still need to test the props again spinning in with load. Went out by myself once for a short spin and turned to 4400 without aggressive trimming o i need to get to around 48-4900 in this heat so when it cools down I am not all over the rev. Should be able to get 5-600 by repitching and labbing without sacrificing too much cruise.

Thanks

Thanks for the info, but that's my normal load and speeds with my 25p m+. I prob couldn't push them any higher.

Someone able to spin 25p m+ already would benefit from these 4 blades and prob not sacrifice any top end.

I guess after they a ounce me as the winner of bblades contest, I will lab mine :-)
Thanks again NL!
