A lot of good info here. I've read all the literature linked in this thread. I'm of the really short femur and long torso type. I use a setback seat post. I adjusted my saddle setback/height to where I could get in the drops comfortably and release my hands without my body falling forward. This has stretched me out and it feels very comfortable to me. However, I can definitely feel a difference when I pedal. I'm used to being right on top of my pedals and now it feels like I'm pedaling from behind if that makes sense. I don't know if this is good or bad.
