I have an '06 Jett 155mm. The cover isn't as nice as the newer Jett (more seams), but those seams never bothered me. It was just too thick, flexy, and too wide in the nose to middle area (rubbed my inner thighs). It's still in good condition. I used it for less than a year.

I've been keeping it around (in the box my Ruby came in) in case I build up some sort of commuter ride or something and don't want a hard race saddle. I don't know if that'll ever happen, so I will entertain any reasonable offers you want to send my way in a PM.

I can take pictures if you want.
