powder claw
In my experience with the power claw on a Twisted M1000, it would descend hills way to fast it was annoying. I talked with Tony Zollinger the other day and he said that with the thicker power claw that they run on their HCR's he hadn't noticed that at all. I think that the newer thicker Power claw would be the answer for sure. If it wouldn't descend so fast I would be in love
