We are trying (so very grateful for the opportunity to TRY a saddle as long as we want) a Billy Cook (Sulpher OK). To me it fits a smidge snug in the shoulders, but she doesn't seem to mind. My daughter rode her for over an hour yesterday and it didn't seem to bother her. There was even sweat on both sides, and being that she's very hairy right now, the amount of sweat didn't concern me. My trainer said to watch for white hairs to see if it's pinching her. How long will it take for white hairs to show up?
I'm not locked into this saddle at all, but it's exactly what we wanted for my daughter, and she being 10 fell in love. She's not locked into it either, but she likes it, it fits her very well, and it's a very good price.
