Update on that saddle-the RXL is awesome! I've been able to ride quite a bit on the road and on the trainer, and it seems to get better with every ride. I don't know if it is 'breaking in' or if it's my rear that is getting used to it, but it feels firm and supportive without hurting even after several hours. I don't miss the center channel at all, and as it's only slightly curved, it is easy to shift from the nose to the back, and center myself as I ride without feeling lumps and bumps and craters. Granted, it's not for everyone; some people want cushion, or holes or whatever, but it may not be needed if the saddle supports your frame correctly to begin with. The trick is finding one that does that. Now let's see if it holds up with lots of use... The days are getting longer and soon it will be light enough to ride when I come home from work.
