In my case, my right thigh tends to run inward (towards the TT, result of an old skiing injury) so I rotate the saddle very slightly to the left so my thigh isn't quite rubbing on saddle skirt. That may also be why my right sit bone dimple is so much deeper. BTW, the rotation is pretty subtle so you have to really look for it. Nose of saddle is offset about 1/4".

One of my bikes has an old Selle Italia. It felt fine. Then I rode one of my bikes with a Brooks Flyer I think it is (?). I'm thinking it's time to replace the Italia with a B17.
