I need your thoughts on this. My saddler recommend this for sox as his saddle needed a bit of flocking and alot of flocking on one side a few weeks ago. Anyhow she suggested this as he does lose topline easy. His left shoulder is bigger in muscle then his right. She said I basically need something to take the weight off it a bit. I did ask if a half pad would work but they don't have the inserts. Like this one does. I am hoping to buy him some thicker saddle pads. But what are your thoughts?
