Well, if I am in the NBHA World, the permanent jobs, which had spoken of these saddle pads. When the clerk said they were absolutely incredible, but they are quite expensive ... I save money for some time to buy a platform for new wheelchair, and I do not know exactly what I want to buy. Currently, my professional choice SMX Air Ride Pad (http://www.horse.com/itm_img/WIP23.jpg) for my barrel horse and seems to be good for him, but his already worn for all audiences. I was wondering if anyone experiences with the CSI-flex pads. Are they worth 300 U.S. dollars is required for them? I do not know any other one has, and that worries me a little. If you rode in one or the other you love? Are the ones that should be cracked?
