I ride in a 17" english saddle. The seat is a bit big but I have to accomidate my legs. I know that a 17" english is about the same as a 15" western. I've never ridden in a barrel saddle before, seeing as where I live it is nearly impossible to find any good western tack, so I was wondering how the seat sizes normally are in comparison to other saddles? I have heard that sometimes the cactus saddles run a little bigger, but I have no experience with billy cook. Do you think that the 14.5" saddles would be too small? Btw, I am 15, 117 lbs and about 5'5". Thanks!
