Decided to go with the TRD S/S. So selling the used URD S/S for $90 shipped to anywhere in the U.S. I will leave the bushing on the ball as I have an extra one.
Making the switch due to the very slim chance that the URD would break the ball or whatever it causes to break on the shifter. The X is my daily and wanted piece of mind. The URD does seem to have shorter throws.
