I recently got a set of powergrips for my bfssfg iro and went for my first ride with them yesterday. First impression: awesomeness. I executed my first couple of skids thanks to them. Second impression: I'm feel like I may break them.

I weigh around 205 - any of you heavier guys like me been using powergrips for long enough to know if they're safe for us bigguns? I did a forum search and see that sticks like Shants nearly makes love to his powergrips, but I got a good 60 lbs on him.
