His owner gave me this thick, stiff pad with inserts to put under my saddle. She tries to protect his back and displace weight. The pad fit badly under my saddle and I let the owner know. Evan though the saddle fits well she wants me to get something. I am now confused whether I should get a gel pad, a good wool pad, a thin line half-pad, or something else.
I would greatly appreciate peoples' experiences. I have done some research, but there doesn't seem to be a definite answer on what is best.
