Well, it does have big knee blocks as well - which are fixed, but I actually really like big blocks (bought the big ones for my Isabell). That said, I also don't really notice the blocks on this one because my leg seems to going in exactly the right spot without any forcing. I'm beginning to think whoever owned it before me was exactly my size and shape.
Good to know about the Stubben. I'm going to get some pics of fit on my horse as well as with me mounted.
