32 envision ,twin 454s, can't quite spin 26 p bravo 1s. I put 23 p mirages on and I get 60 mph at 5100,seems like a lot of slip? I want to try either 23p rev 4 or 24p bravo 1s. What is anyone's opinion? Thanks.

I believe you will like the Rev 4 performance right out of the box. The Bravo propeller will need some adjusting to make it just perfect for you but will ultimately have the best performance.
We have these propellers for testing without having to buy should you wish to do so.
