Ironically some my second pair of Syntace Stratos bars just arrived in the mail today.
I have broken my wrist twice and I have problems as well, but since I switched from RB021s to the Stratos (with cross levers on top) I have not really experienced any pain. As mentioned above, they have a bend which is more comfortable than any other bullhorn Ive used and she can get low on the horns when she wants.
