I need to proofread before I post...
FYI, re: restricted hip angle:
shorter cranks offer a less restricted hip angle. And studies have shown that crank length is not correlated to power, so feel free to go shorter with impunity. (Within reason, of course).
in before anybody else:
it's not the size of the worm, it's how you wiggle it.
