Does the thickness of the saddle pad affect the way a horse may ride or respond to the rider? I currently have to saddle pads, one is a felt lined with breathable holes along the spine that is about 3/4 inch thick, it has the neoprene material sandwiched between the felt. The second is a full wool blend that is about 1 - 1 1/4 inch thick. I have been using only the felt / neoprene one under my heavy roping saddle. However I am concerned about my mare being a sore back. I have not seen any rubbing issues, except that when you brush her down the loin she kinda responds by dipping the back down as being a little tender.
What type of pad may help her? Saddle fitting issues are good, saddle fits her.
