Your pelvis isn't prefectly symetrical so it's fairly common to twist the saddle to one side or the other by a couple mm to accomidate asymetrical sit bones. To be frank, I had the exact same problem on a 143 Romin.The Romin required me to keep my pelvis rotated to the extreme and was the most painful saddle I've ever ridden (YMMV!). I am now on a Fizik Antares and loving life. One thing I did like about the Romin was the way it held the pelvis while deep in the drops. I might consider a Cromo (more padding) version for a TT bike. So I'd probably go with the Toupe if only because it's a flatter saddle and *I* seem to be more comforatable on them.
