can someone please tell me why top quality wool felt pads aren't seen in endurance very much? The woolback seems ok, but not very substantial, seems like it wouldn't give much pressure relief.
My guess about the felted wool is that it would be rather hot over time. Endurance riders want a pad that is going to help dissipate heat from the back.
I am not sure what kind of woolback you have experienced, as the ones I have used are quite thick. We currently use toklat matrix woolback pads on both the boys with great success. We have also used skito pads and liked them.
I personally have never looked to a pad to give "pressure relief" unless I was talking about a treeless saddle, in which case I would def use a pad with inserts (a skito, in my personal case). A treed saddle is its own pressure relief, assuming it fits properly.
