I haven't seen any reviews on this yet, so I thought I'd put one up just in case anyone was on the fence about RTF.
I got my Victory last spring and have ridden in it two to three times a week since then. I absolutely love it. Because of the RTF system (which is super easy to use!) I can fit it on nearly every horse in the barn. Unfortunately it won't fit the really high withered TB who also has barely any topline, but that's because it's a wide tree. It's really comfortable even without the plushy seat cover I got after the second week, and the leather is soft and pliable right out of the box.
Just a warning though; the saddle DOES squeak. I'm not sure why, because I've oiled and conditioned the crap out it and I can still hear it when I ride. My friend's Circuit also squeaks though, so it may just be a Circuit thing. You should also know that if you don't regularly adjust the gullet it will stretch just a bit. I usually leave mine nearly as wide as it will go, and I've had to narrow it just a smidge twice since I set it that way.
I don't know if it's just the oil I used, but my saddle did darken a few shades when I oiled it the first time. I don't mind, I actually like it better like this, but it's just something to keep in mind.
All in all it's a really nice saddle for the price, the horses seem to like it and it's very comfortable for me. Since I've had mine another girl at my barn has gotten the same one, and she loves hers as well.
