Hi Hog,
I don't know the specifics of the seat adjustment thing, but I'd agree with Hunter that you should have a slight bend in the knee when you're at the bottom of your pedal stroke.
For myself, I just adjust the whole set up until I'm comfy. As for suspension seat posts, I don't find that it robs me so much with bobbing up and down, but I guess it depends how soft you run it.
My post is set up regular, and works fine...
Rich :dance:
