I’m curious about these and other non-traditional saddles. Does anyone understand why flap vs. flapless would make such a difference in rider stability? The Clayton study says, “The improved stability was thought to result from the absence of saddle flaps allowing the rider’s thighs to lie in more adducted positions, which facilitated the action of the lumbopelvic-hip musculature in stabilizing and controlling translations and rotations of the pelvis and trunk.” It surprises me that a thin piece of leather (or two pieces, I guess, since none of the traditional saddles in the study were monoflaps) under the leg would matter so much. Does that mean you lose the benefits of the EQ saddle if you ride with flaps? I would think the difference between the EQs and other saddles would be more due to the tree and panels than the lack of flaps.
Can someone educate me? I love the idea of evidence-based tack, but I’m more likely to buy something that makes my horses more comfortable (i.e., Fairfax bridle) than I am to buy something that makes me more stable–though I guess indirectly that might make my horses more comfortable! Also, a study with a larger sample size would be nice to see.
