1. Fizik Aliante (I've had two, inc one with broken carbon rails that Fizik quickly replaced sans purchase receipt).
2. Worst are Selle Italia slr, flite, any of the 'stock' saddles I've tried, and any saddle I've ever tried at the start of a season.

The dude who got the nut stuck in his cut-out going over a speed bump -- #$%^ I just can't get this out of my mind. Mental note - never, ever get a spit saddle...
