I've only built 2 frames with it but, I really like working with it. Machines nicely and isn't to much trouble on the bends. The first frame was a BMX frame for me and the feel of the ride is noticeably different from something like True Temper. Hard to describe.. feels like it stores energy taking of jumps. Maybe springy but, not in a bad way.
Thanks for offering the 921! -Mike
