Update: Okay I got a small piece of the Backsaver Foam (
http://www.pegasusautoracing.com/pro...asp?RecId=3124 ) for the bottom half of the seat and WOW!!. It's really a very dense version of memory foam and really gets rid of the preasure points. Cuts with scissors pretty easily. I put it between the seat and the original breathable foam to keep things cool. I've gone 90 minutes without having to adjust once and I'm dying to go longer. It's really not that heavy either. About 250grams. If you're a gram-shaver you may not want the extra weight( I shave weight by using the bathroom before the ride) but if you have "recumbutt" issues, it just might work.
