See my 2nd post....
If you rarely hit the highway, the 16T is a definite improvement, IMHO.
This season I'm doing a lot more x-country so I actually like the stock gears.
I posted recently in the "log your rides" thread about my trips up into the mountains around here with both the 15T and 16T gears. It turns out I really like the stock gears best when riding at speed in the hills.
