Wow, I'm not the only living crash test dummy around. Mines from a horse. The right side is my longer and broken side. I appreciate all the help. I have been using thin shorts, so perhaps the thicker shorts can help with the back, and a thinner saddle can help keep the crotch happy. I was really happy with the ruby for a while, which is super flat. All of a sudden my back just started screaming. I do get shots in the back and I think I'm due...it SUCKS getting old. I will definitely look into another SSM.
