Dude, i read your whole post and in my opinion, it sounds like your clutch is not adjusted right or something.... dont you run i hydro lever? I had one that gave me fits when it came to getting any REAL adjustment. I finally went back to a standard cable/lever setup,,,problem solved.
I say that its prolly an adjustment issue for that reason AND the fact that myself and several others ARE putting down 75-90hp on the Driveline/R1 clutches ,,,in that sand with paddles, and AREN'T burning them up. If they will stand up to that abuse,they should take Hare Scrambles fine.
Something to look into at least.
