You can't confuse hydrodynamics and aerodynamics. They work pretty differently. We're not trying to pull your leg here. Simply google "lowest cd shape" and you'll find a million references to an airfoil (aka teardrop). Dig deeper and you'll see why the bulb is better than a flat front or a pointy front. Better yet, search around this site. This dead horse has been beaten into a unrecognisable bloody spatter.
