SCurve,

Shorts and saddles are very, very personal things and what works for one doesn't necessarily work for another. That said, I've just recently had horrible experiences with both versions of the Jett saddle (the one with stitching and the one with the smooth cover). I experienced chafe on either side, as you described, right at the pantyline - and I had the narrow saddle.

I also ride in the Sugoi RS shorts and they're great for me - not with the Jett, though. Nothing for me was good with the Jett. My saddle now is the Aspide Glamour, which is wide through the rear, narrows significantly at the nose, and has a little channel, as opposed to a cutout, to relieve pressure at the front. Not having a cutout, and having good shorts, took care of the chafe issue for me.

Good luck! I think the shorts/saddle thing is something everyone has had to work their way through.
