Wintec System (20 characters) ?

Hi, i was wondering about the Wintec interchangeable gullet system? I have to buy a saddle for lessons but I'll also be using it when i get my own horse. I don't want to have to buy a new saddle because the one i have doesnt fit my horse's withers! haha. help? Do you use/have you heard good things about the wintect gullets? Thanks guys!
