I would have went with it being too big if anything. That's why when they recommend two pads I didn't think that would be a problem and might actually work better. Even with my old wore out pad it tended to roll it seemed. The first day I rode him with the new pads it was even worse, but I first thought it was because the pads were new. But those dry spots really bother me and I think warrent haveing it checked by someone who knows. I know soreing up a horses back can really screw them up for riding. Can't says I blame them either.
