Thanks for an excellent write-up. I've been using a Flite gel but find it slopes too much for me. So, I switched to a Selle Arrowhead which is flatter but definitely lacking any "flex." Arrowhead is a good name for it. If it were a bit softer I think I'd love this thing. So, to cut to the chase, the demo kit sound like a great idea. Thanks for the heads up.
