saddle advice for my gf?

[OakLeaf]

move the saddle as necessary to get this centered under her

I tried this after being advised to do so (by a guy of course), and all it did was wreck my KOPS and give me foot and leg cramps. My experience is that fore/aft saddle position will not change rider position on the saddle; that's determined by anatomy and handlebar height. In my case, I was sitting too far forward on the saddle for a simple reason: it was a pear-shaped saddle, and I need a T-shaped one. My thighs were forcing me forward onto the nose.
