Other than the mono vs dual, did you feel like they both rode the same in terms of balance and positioning?
The lexington is a monoflap, the palm beach is a dual flap. I have an 18" 3AA palm Beach. If you plan on ever showing in hunters/equitation seriously, you should go for the palm Beach. Monoflaps are not “traditional”.
The Lexington may feel closer contact because of the single flap. The palm Beach comes with the " second skin" option, where the sweat flap is made from thin calfskin. I opted out of the second skin because I didn’t find there was that much of a difference. The second skin wears quicker than a normal sweatflap, and that wasn’t worth it to me.
Both are really nice saddles, and I would suggest riding in them both if you have a chance. I love the 3AA flap for xc, when I jack my stirrups up and need something extra forward.[/QUOTE]
