What kind of horse are you riding? What kind of build?
I could see how the M Toulouse build might not be the best for longer legs. You told me you're on the shorter side, so it may work out for you..
I would suggest either a Close Contact saddle, or an All Purpose. Dressage saddles can be kind of restricting, when you just want to have fun on the trail. CC allow more free movement, and are more suitable for the flat and over fences. All Purpose, are nice, but have the seat of a dressage saddle (or most do), and can give you that same, locked in feel for playing with small jumps. On trail, they're nice though.
