I love mine my 18yr old TB has had his since he was 6yrs old and had no problems. Tried it on my New Forest and he moved much freer in this than the extra wide Huntsman saddle that we got for him - after trying about 15 different styles and shapes. My 5 yr old we started in a medium wintec and he muscled up over the withers so he also is now in a Balance saddle. They are great as long as they are used correctly
