Hey Jeff, Figured you would be watchin this thread. Your clutch rocks man!! Couldn't believe how much slip we were getting on our 50HP asphalt drag Shee. Had to learn holeshots all over again cause it just about killed the motor it clamps so hard...Anyway, We're putting a cub together that should run 100 horse. Would you recommend the same setup (remember we bought 2 from ya) or is there a different set of fibers that would be better for this setup? Ted from Ohio
