Good news update.

Just really quick because I have no time but I just wanted to thank everyone for thier input on Steady's issue.  I made a couple changes today: Used a different saddle pad and added shims to my halfpad thinking maybe since he has lost musculing that my saddle is getting uncomfortably close to his withers again.  I don't know which or if any of those changes had anything to do with it or if it was just coincidental but today we have a nice ride.  No twitching, bucking or nipping.  He worked fairly nicely even though it was a very windy day and that makes me sigh a little bit of relief.
