Hey guys, ended up buying some Calf Cuffs instead of the knee bar that comes standard, the knee bar was hurting my leg, so yeah, anyway, now with the calf cuffs coming and me adjusting them to the right height and everything (Thanks Jason for the tutorial you posted on the calf cuffs). Although, after using them, I've found that I can't tighten the pinch clamp enough to stop the new calf cuffs from twisting, after tightening the clamps to the point of actually bending the plastic into the metal, they don't twist so much, but I'm worried about plastic breaking. Is there anything I can do about it? The only thing I can think of is to get some tape to put around the frame that holds the cuffs in place or keep tightening them, which I don't feel comfortable doing.
