Do you tighten his girth all at once? Make sure you only put it on the loosest setting when first tacking up, then stretch his front legs forward to make sure there is no skin pinched in his armpit behind his shoulder. Then you can gradually tighten the girth (make sure your saddle hasn't slipped and that the pad is pulled up into the gullet so it isn't putting pressure on his withers). It is best to tighten 1-2 holes at a time, and then walk him forward a few steps between each tightening. Give it one last check before getting on.
If you think it is saddle fit, you could post some pictures of how the saddle sits on his back- both with and without the fleeceworks pad, girthed and un girthed and everyone on here will be better able to help you. Does his back show signs of tenderness or soreness (flinching when you run your hand down either side of his spine?)
