Ok, since buying my horse and switching him to English I have been riding him in a friends wintec 250 AP saddle while I was saving money to buy my own (read poor teenager syndrome lol). It fits him like a dream, and he never had a sore back and built top line great. However, she said that she stopped using it on her horses because synthetic saddles are harder and hurt their backs. I fail to see the logic in this, myself. I found it FAR more comfy than any leather saddle I tried, it's waterproof (I'm an adventurous rider lol) and jitterbug moved out great in it. I managed to get one in the correct size for $450 with the easy change gullet and riser system in a cyber Monday sale. Has anyone had any negative experiences with wintec? Have I wasted my money? He has made amazing progress in this model saddle. I can hardly remember the last round of rodeo bucking (he has not had the kindest experience with people in the past) or crazy bolting.
