The stamp on them is "SPHEREBAR" - like a bowling ball material. I guess the fact that I can now move them by hand (not THAT easy-but do-able)is a good thing - no? <BR>

Yes. Extra motion from looseness in that area subtracts from the small bar motion that transfers weight. Hall's original 'sphere-balls' used a poly ball in a molded two-piece plastic housing glued together on assembly. A separate aluminum top took the stress of the two mounting bolts. So those early '90s units were kind of stiff too but quickly loosened up on the road. Glad it worked out- J Deryke<BR>
