Wither pad, riser pad, or half pad?
I have an older Passier Hannover dressage saddle, medium wide (although supposedly they run narrow), that I have begun to take lessons with. I hop between different horses, gaited and non gaited, so far with very little issue. It is a good saddle, well balanced, and I have never really needed more than one blanket (and sometimes a thinline) with it. However, recently I've been lessoning on this really warmbloody built QH with it, and the saddle marks left behind arent entirely even. Along the spine is fine, no big pocket marks or anything unusual. However, the front of the saddle leaves a heavier sweat mark straight down from the wither by the shoulder under the saddle flaps (not directly on the wither, but below it just behind the shoulder blades). Now, I would assume this horse, with as much lessoning as he does, has simply grown quite wide with new muscle, possibly to wide for my saddle. He's not sore, and he willingly lifts his back and collects under me.
My question is, aside from the obvious 'use a different saddle', would a wither pad, riser pad, or maybe even a simple normal half pad on top of my usual thin square dressage pad lift the saddle up and give him more shoulder space under my saddle? It was suggested to me to possibly use wedges to lift the saddle, I havent tried it yet. I was curious though as to others thoughts on the subject, if lifting with a thicker pad to make the saddle sit higher might solve the issue, or using riser pads/wedges to lift the front of the saddle is a viable option to.
I can use my instructors saddle, or the horses owners saddle, which both fit no problem (although may not fit me so well), so its not the end of the world if there isnt a fix for my saddle. Im just rattling thoughts around my brain from when I was last through the tack shop. I need to go back to pick up a new girth, so was hoping for some insight towards if I want to purchase a new pad while I am there.
Thank you for reading and any suggestions,
Think of it not as a failure but as a success in how not to do it.
Don't look in a horses mouth for a gift.
