how's the balance of the clamping hub? do you think it is better than associated's way with the threaded ends on both left and right? I don't know which axle to use. I have an associated graphite axle and a IRS. I like the IRS because it has the "D" diff rings but the associated seems good because of the threaded left end (easier to adjust the endplay) but no "D" diff rings. Maybe I'll just get the clamping hub.
