I have the Denisse, I was told it has the longest flap on any of the close contact M Toulouse models..
I do find it puts me in a weird position. If I go back to my old Crosby xl which I -LOVE- and is much higher quality in my opinion.. My equitation goes back to near perfect. In the Denisse, I almost have a chair seat, and have to fight myself to put my legs back a bit further. It's not that big of a deal, and it's the only saddle that I've found that fits me and my horse aside of the minor chair seat.
But, I mainly use this saddle on my OTTB, where I kinda tense up. When I use it on my other seasoned horse, I can easily fix the chair seat, as long as I keep thinking about it, if that makes sense.
It's got non-movable knee and thigh blocks which I find to be a pain.
I'm very tall and thin 5'7 110 pounds, so I only -need- a 16/16.5 seat. But even with a long flap, most saddles didn't fit me so I went with a 17.5 Denisse.. I had a real struggle with finding a saddle that fit, and I didn't even set a price limit..
