My Selle Italia Gel Flow has been pretty descent. But I think I'm going back to Specialized with the larger relief channel. I know Selle has one also similar to Specialized, but the weight of the Selle is kind of silly for a road bike race saddle, nearly 300gms.

I can shave anywhere from 80-140gms off the bike weight just by switching back to Specialized, plus pay less money for a Selle equivalent. Overall Selle makes a nice saddle, no other real complaints beyond the personal weight and fit issue.

That SLR looks real similar to the other models, just a lighter, less padded version.
