I've decided to get a Wintec saddle, with the CAIR panels and gullet change system. The question is, should I buy the 500 dressage or the 500 all purpose? I've had an AP saddle in the past and i didn't like it, but that may have been the make. Whadya think? Are APs worth the purchase, or should I start with the dressage and save for a jumping saddle?
