Like everyone said in the earlier posts I'd ditch the 3 blades and go 4 blades. On a Formula straight bottom the Hydromotives are the way to go unless you want to have a set of Bravo's labbed. At that point the Bravos are better but the cost is twice as much. I have a nice set of Hydro 25's I'm selling if your interested. I switched to labbed Bravos. The Hydro's are faster on the top but the Bravos accelerate better and IMO feel better overall.

I need to baseline with new engi we and see where I'm at.... Then go from there I got a set of 27 hydros but I seriously doubt the heavy Mistress can push them... The drives are so deep on a trs and a heavy mistress I still can't see a 4 blade being faster up top then any 3 blade... Cruise yes but not top end...and a little slip will be easier on drives, guess I have lots of thinks to play with once I'm back in... Hopefully this weekend
