Hate to shoot down your theory, Sin, but I know two maybe three girls who are at least as good a climber as me, my GF and two of her biking buddies.
My GF can stay with me on my best days, and on my lazy days she has no mercy. I can live with it because on HER lazy days I make sure I get her back . . . male ego and all, you know what I mean.
My GF's friend is short, about 5'2". I don't know what she weighs, but she has these huge thighs which exhibit no definition at all. They're just blobs, so to speak. I would put my money on her against any man I know. She will kick my @$$ on any hill, and yours too, any day of your choosing.
I had heard that she lives on this tough hill so anytime she bikes she has to finish up on this hill. Just this past winter for the first time I went to a party at this friend's house and I finally got to experience this hill . . . in a car!
Now I know why she's such a strong climber. F'ggetaboudit!!! I would move!!
