hex balls and side links
dx6-
I too have broken hex balls on my knife, when I first got it I was hitting more dots than apexes. But it was actually the screw that broke and not the ball itself. Steel screws solved that problem. They aren't red but whatcha gonna do...
Storm-Those screws are really short but they are as long as they can be without bottoming out in the hex balls. The Speedmerchant side links are way better (one of the reasons I'm racing my speedmerchant and not my ck now) but the length is different so you would have to drill new mounting holes in the chassis to use them.
