Just for hoots and nannies, I am in South Arkansas so weather changes, DAILY, but am running a 06 classic and usually run a fair load of gear. I had been having trouble hitting the Rev limiter and went to a 26 Fury, now in the dead of summer I am riding on 5400 at WOT and flat more hauling (a donkey)!!!! In late Sept, with cooler waters my RPMs bumped on up and she was screaming!!! I have also ran the 27 tempest, top end was real good, but not as good a ride as Fury. Oh yea, the majority of my runs consist of two “big ol boys” and their gear. Hope it helps. Try to find some around your club and test them out. But try different props on the same day under the same load, weather and etc….and keep you some notes on speed and RPM and holeshot, that way when you find a prop you can tweek your JPlate
