I don't know the Torsion, but I have a Cheyenne.
Both horses I use it on move very well with it and seem happy.
I had to get acustomed to it, I didn't initially like the feeling of being "perched" away from the back. I think it molds to the horse's back with time and that feeling lessens.
With a treeless, you can put it more forward than a treed saddle, but it will always settle back where it belongs. I think you and your horse might be happier in a size 1. On most pictures, the Barefoot seemed more level than the Torsion. Is the Torsion pushing you backward while riding?
With any treeless, I'd put a pad with inserts to help clear the spine.
The pommel: do you know what size you have? If it's too narrow, it can be a site of pressure/discomfort on the wither. You could have it changed for a soft pommel, especially if you ride different types of horses. That's what I have and it didn't change the stability of the saddle.
I really think the Torsion would work with a firmer pad. The Skito has optional felt inserts, I need to talk with Tom at Skito to see what we can do.
Looking again at the picture, I see the Torsion did slide back on Chivas while I was riding. It does sit a little different, the pommel felt wider on the Torsion than the Cheyenne. I at first thought that was better being wider, but now I wonder if it was pressing on his withers or something.
Chivas may be happier with the Cheyenne cause it feels more like a treed saddle that he's used to.
Overall, I am not sorry that I bought them, and I still think treeless is the way to go with him. I am sorry I didn't spend a little more and buy the Cheyenne from somewhere that I could exchange it if it didn't fit.
I think the Torsion looks like it sits better on most of the horses, except Drambuie. The Cheyenne should be better for him, but since I have a Big Horn endurance that fits him great, I probably won't need the Cheyenne for him.
The Cheyenne seems to be popping up a bit in the back on the pictures, I wish the billets were a V shape adjustable kind. But of course the saddle goes down on their back once you sit in it.
