I have an ovation hunter saddle, I believe the seat is 16.5". Anyway, people keep telling me it's slippery. Recently my trainer told me it was slippery. Now, I asked her opinion on this saddle before I bought it because the last one I bought was not right for me...seat too big etc...it was also imitation leather, the ovation is leather. So I'm wondering if there's something I can do to make it less slippery??
