I have a centerforce single friction in my rig and I really like it. It is easy to drive like a stock clutch. I don't see why anybody would need any more power. I have never noticed it slipping at all on me. Even dumping the clutch hard with both cases engaged in thick mud has never show any signs of slipping. I would be curious to drive a rig with a dual friction clutch to see what the real difference is. If the single is good, I'm sure the dual friction is better unless it sacrifices driveability.
