Received my new Koobi AU Enduro last week, slapped it on the Specialized (and moved my old SI back to the old bike), then went on that Diablo ride Sat.

Granted, I didn't do the whole 13 mi climb, but the 6 I did was planted firmly on the new saddle.

Fabulous! It has a slightly narrower nose profile the my old SI and no "new saddle" whoes at all.

The AU Enduro comes with gel as well (which I did not get). I did go with the magnesium rails.

I are a happy spazzdog
