Farther the drop, the more sensitive the position. I rode shallow drops for quite a while. Nice.
I've got my position just about dialed in - virtually the same as it was in 1974, but I've been working on it lots. 9 cm drop. And that may be just a bit aggressive for short rides, takes me a while to work into it. On the other hand, it's great downhill and into a strong wind! But I'll flip my stem sometime and see if 2 cm higher is a good thing for me.
