I threw 2 blades on my 26 trophy last weekend, looking at getting a new prop. What kind of numbers are you getting with the 25 fury on 200 opti on the p4? I run a light 2 medium load and fish mostly south Mo, Oklahoma and some Arkansas so elevation should be no question.. With the 26 trophy I was turning 5650-5700 rpm most of the time.. I like the idea of the new material in the fury plus the midrange and top end. Need imput have a Heartland in a few weeks need to get boat dialed in so I can concentrate on fishing thanks, Earle Hammond http://www.knuckledownlures.com
