Welcome to the forums! CTOM already pointed out the differences between the es and cnc molds so I won;t go there other than to say that if you plan on selling baits your customers will dictacte wht you should get. Personally, the es molds are a much better bargain and shoot exactly the same baits that will catch the same fish. As far as what baits you should make, I would divide them up by water column. Say, frogs for the surface, swimbaits and curly tails for mid and worms crawfish for bottom work. Then buy according to your fishing preference. My two pennies.
