Thanks Guys.... I'll stick to the dog bones then. I have the HD now and they are wearing well enough. They are a bit twisted but not too bad it's the cups that are really showing some serious wear. I'll replace those soon. I started driving a little bit smarter now (still a noobie) getting the feel for jumping so I don't lay on the gas/brake when landing. The center Standard Duty bones are not twisted at all so the advice you guys gave in one of the other threads seems to make sense. Thanks again for your help.
