I tried a $160 Selle Italia Flite with Ti rails for a couple of weeks, never could get used to it. It was too narrow for me I think. After that I got a $35 Selle Italia X1 that's a bit wider and feels MUCH better to me. No pain or fatigue whatsoever after a ride or days after. It's not quite as light as the Flite, but it's still lighter than my stock Felt saddle so that's good enough for me.
