I have looked and am still coming up blank. is there a rule of thumb for determining the size of lip for a crankbait? Say I want to make a wakebait, I know that I need a rather steep bill angle, but is there a way to determine proper length and width? also as I have been studying Karman vortex streets, I see that that creates lure action. Would a bait with a flat face that tapers back have good action, or would the taper cause the vortex to smooth and lose action?
