That seat style thing really comes down to experience. I'm about the same size as Richard and find a thigh bolster more comfortable, but suspect that would depend on the rest of the seat configuration. For years I'd heard folks rave about a Tea's Design seat that has that same pronounced thigh bolster as well as a pronounced lumbar bulge. I finally tried a ride on one of them and found that the lumbar bulge started causing me grief after only about 20 minutes of ride time. We're each built differently, and maybe some have had other lifestyle issues that result in back "problems", so I don't take others experiences as replicable to mine.
