really? take 3 pics of yourself on your bike with your saddle where it is now, and then with the saddle bottomed out fore and then aft on the rails with your feet at the 3 and 9 position. it will change your knee angle tremendously.

some people are super sensitive to fit, but if you really size your bike like that Brian, you are either missing out (as Commodus said before) or you're performing well but strangely insensitive to fit.
