When I was fitted at the shop when I bought the bike they did the whole plumbob thing and 30-degree bend thing and since then I've never had any knee problems and at the end of a hard workout my thighs feel pretty evenly worked-out (sore glutes, hammies, and quads) so I'm guessing the saddle is right.

Then again, there's that article on Sheldon's site about KOPS being a bunch of BS (just look at time trial-ists position), and that it's mainly about rotating the rider around the BB, regardless of gravity. Of course, TTers use aero bars to support their weight.

I've heard about moving the saddle back to take weight off the hands. I find it interesting and I think it's possible I could get away with it without being "stretched out". Maybe I'll give that a try.

It's funny, but every little movement requires a long ride to find out if it worked. 1cm = 40 miles, haha
