I have slung blades off of three Bravos in the last 18 months. Soooooo, instead of buying another Bravo to sling the blade on, I bought a 31 promax. I am not trilled with it…85 light and felt sluggish. The reason I bought it was because I borrowed a buddy’s 31.5 Promax and LOVED it. I couldn’t find a 31.5 so I bought the 31. It doesn’t feel nearly a peppy as my buddy’s 31.5. Can that 1/2 pitch make that much difference? My buddy knows a lot about props and he said it does make a difference as that 1/2 pitch is all cup to help lift the bow. Do you guys agree? Think i can get some cup added and make it like his 31.5?
