Aventera Two,
Take a look at the various Barefoot saddles on this web site:

I’m not trying to offend anyone, please, this is just my opinion, this “type” of treeless saddle, which IMO includes most of the treeless saddles that have the removable seat on top, are very flat, it’s in their design. I owned a Barefoot London for a while, owned a Lag also. They actually felt better, less flat, without that silly thick seat on top.
Look at the pics of the BMSS here: http://www.sportsaddle.com/noflash/gallery/endgallery.html These saddles have a bit more “twist” to the seat. It’s largely because they have a pieced seat, seamed down the middle and made with a contour to it.
I found it hard to even find a picture of a torsion or Barefoot without it’s removable seat in place. these saddles for a large part are made as a flat one piece pad. Without the pommel attached the saddle lays out flat when set on the floor. So they need help from pads with inserts and maybe creative cutting and shaping of the inserts to get more of a “twist” feel. IMO they feel best when used on a horse that isn’t flat backed, so does the BMSS. But, interestingly, I’ve used a BMSS with only a plain fleece pad under it in many endurance rides, no inserts, and there is always a long dry strip down the horse’s spine, no saddle pressure, because of the contour built into the seat. Of course, I do hours of posting, not hours of sitting.
No, I’m not fond of the flap under my legs, covering the cinch and stirrups rings. The newer BMSS have a bigger flap made of heavier leather. Pic number 27 in the photo gallery above shows the current style of BMSS. Wish the saddle maker would experiment with a “english” style saddle, but they don’t seem interested.
A note of advice. The endurance models come with the stirrup ring placed very much under your hip, more so than any other saddle that I’ve used. If you have bad knees, as mine have become, you will find yourself happier if you shorten your stirrups some, get your knees further ahead of you, where they are off the bulk of the rings/rigging, and where your horses barrel is a bit more concave, the pocket just behind the shoulder. I’m sending my BMSS back to the mfgr this winter to have the stirrup ring moved further forward. I bought this saddle used. If I had ordered one I would have had the ring placed an inch further forward.
I do like the Sensations, they are the most comfortable “English” style saddle that I’ve tried so far. I haven’t tried the Moffett or Ansur saddles as they aren’t in my price range. I competed Mouse all this last year in the Sensation and had to come to the conclusion that the saddle isn’t as good for his back as the BMSS. I know a lot of people are using them for endurance but I’m seeing back changes and other evidence that convinced me to switch back to the BMSS.
I also had a FreeForm saddle. This one didn’t work for him. I had ordered the short base model but Mouse is butt high and still had loin pressure in spite of playing around with special pad inserts. I do know that they work great for many rider/horse combos. I sold mine. Oh, IMO they are very close contact like. Again, they have a flat pad as a base and I never got the feel of having a hollow for my knee to fit into. I didn’t have a model that allowed for adding the velcro knee rolls. I am short legged and I found that my knee was above or behind the knee rolls on the FreeForm, BF London and Treefree saddles. The Sensation saddles have a built in twist and better shape that you sink into. You can place knee rolls under the flaps where you need them, a couple of different sizes. But the saddle doesn’t have enough structure for heavier riders and they have very soft, thin leather, too thin I think, but super comfy.
I have certainly spent a lot of money trying saddles over the years, I do want to try an Ansur by the way. I have a couple of endurance riding friends that are using them now.

Your girlie is built just like my Monster and my treeless fit her perfect. She really liked it too. The saddle was just doing something weird to my hips and I have some bizarre problem going on in my joints or something right now anyway. Oddly enough, bareback is more comfortable for me on her.
It’s why I no longer have Butch. Watch, though, I never came to grief on the big bad bucking OTTB–it’ll be the little Arab that gets me.
