Thanks guys. I am very impressed with it. This company does good work, especially for the price. Of course, it isn't as super high quality as one that would cost $2000 but the only thing I have found on it so far that is a little bit off is that there is a piece of rawhide underneath the cantle roll that is a bit rough, but shoot, it's not like it's a show saddle or anything LOL. All that matters is that it is made sturdy and is comfortable for me and my horses. I had the option for tooling but I got the saddle made full roughout and roughout and tooling just don't mix. Plus, it's too hard to clean the mud out of tooling

Dee: I honestly don't know what all seat sizes they cover, it wouldn't hurt to call and ask. Though you might want to go to a local tack shop and just sit in a bunch of their saddles to find the tree that is comfortable for you. I love the modified association tree, it has a deeper seat and feels so much more secure than any other saddle I have ridden but some people find them uncomfortable.
As far as I know, this particular company only has one size of tree for horses, it is a FQHB with a 7" gullet. Fortunately, that fits most normal stock horses. They have all different kinds of tree options for the rider. I was able to ride in my brother's saddle enough to find out that was what I wanted so that part was pretty easy. I just told them the basics of what I wanted (I'm not terribly particular) and let them have at it. I think I know what you are talking about as far as twist goes, my Dad has all his saddles made with a very flat, very wide seat because that is what is comfortable for him. I can't ride in a saddle like that for more than about 45 minutes before my hips are killing me, I have to have a more narrow saddle. This one is just a touch wider than my roping saddle but it is deeper too and my weight is balanced different. I can ride 4 hours in my roping saddle and I'll be hurting but I went out for about 3 earlier and I came back in feeling great (well, my knees and ankles were sore but that's just because the stirrups aren't set yet).
