I second the idea of talking to TE. When I realized that I was sitting *just* at the edge of the Terry chamois (I think it is the same as the Shebeest one), I had TE measure a bunch of chamois for me. At the time Craft had a wider chamois. I found the Craft short too short, but it might work for you.

Currently, I only wear Boure Elite shorts ( http://www.boure.com/1650.html ). I have them make me up a custom short because I want a longer inseam. If the chamois worked for you, but you didn't like the length or the rise, you could try talking to them. I've been quite pleased with their customer service.
