The only western saddle I've ever ridden in is a wintec... but what I've found is that it's pretty difficult to fit. We got one for our RDA branch here for some of the kids who find English saddles difficult, but it fits ONE horse out of the twenty riding school horses. It has a weirdly wide, flat fit... tried it on my old horse one day, and he hated it with a passion.
I know next to nothing about western saddles, but I do know that I wasn't impressed with this saddle for the use we had for it. It also felt very stiff and not particularly comfortable, although whether that is just down to me not being a western rider and not having a western position I don't know... just my tuppence!
