Lookin for the best set up without buying the team tied secondary. Right now I am using the springs from the epi mudder kit with 1/8 shim in secondary. I have rooster weights and have been playing with profiles and 54-58grams. 30″skinny backs or 30″skinny/wide mudlites. I find it pulls better with heavier weights and stiffer secondary spring, but little less rpm(6800) If I just run the epi springs with no shim, and enough weight to get 7200, belt grip suffers, doesn’t feel like it pulls as hard up hills and mud. The 54g epi weights have a much higher stall with the same spring then the roosters(3-400rpm) Wh Would like to hear others test results and experiences.
