Performs well. You will lose some top end,but holeshot and handling are phenominal. I have rune 25 and a 26. 26 runs real good when weather is cool or warm,however when the temps get up the holeshot is awful with a full load and livewells full. The 25 is a good all around. I have a 25 Fury 4 for sale if interested PM me.
Been running a 25P 4 blade in my Cougar FTD for over a year. Hole shot is great when boat tanks are full, live wells, tackle, my big butt, and two Talons. Gave up a couple of MPH on top end, but I am good with that. Still runs 70 mph.
