I hopped on him to test it out. He did not react badly, great. As we walked around to warm up, I could tell the saddle was a bit tight on his withers. Then when I asked for trot he did, but reluctantly and was quick to transition to walk. Roscoe does not seem to want to move forward if he has any pressure on his withers. I did not have a whip with me to see if he would move on if encouraged. Instead I think I shall bring the Thornhill Germana and try that on him. It is a similar saddle but wider. I bought it for Barry using a wither tracing only to have him outgrow it in months. I really love changeable gullets. They make life so much easier with a growing, developing horse.
Leave it to Roscoe to be narrow around, but wide on top.
And I still have to pack for me. Too much stuff to do and not enough time.
