My horse is starting to get on in years, having just turned 21. He is in still in great shape, being ridden about 6 times a week and jumping - smaller jumps than before, but he still loves it. However, I can see some inevitable changes in his body shape, namely that his spine is becoming slightly more prominent and he has lost some fat around his withers/spine. (He is still at a good weight overall, although I have had to increase his food to maintain it.) I was riding the other day and noticed that my saddle is losing some of its wither clearance. I want to make sure that I fix this before he gets any back soreness. His saddle generally still fits well otherwise, so I am hoping that I can just change the pads instead of getting a new saddle.
I’m currently using a regular square pad and a basic Thinline pad. My trainer suggested using a wither relief pad with a cutout to make sure that his withers and spine have enough room. I’d like to spend less than $100, so am considering these two pads from Dover:

Or is it worth spending more to get a saddle pad with adjustable shims, in case his shape changes more as he ages? Anyone else have suggestions on how to adjust saddle fit an aging horse?
