center-pull brakes: shorter v. longer straddle cable
so if i remember my high school physics correctly (quite an "if") a shorter straddle cable on a center-pull (caliper) brake will yield greater stopping power (or at least a tighter squeeze) based on the angles, vectors, and all that jazz. however i've been told a couple times (by people who's bicycle knowledge i generally respect) that a longer cable is the key to greater stopping. i searched through here and sheldon's without any real answers. a few notes here and there hinting that my assumption is correct, but i wanted to address the question directly. anyone know for sure? thanks!
we all know what they are, i just like pictures.
