Nothing on the planet (except a Zorn machine w/ expensive molds)is faster then a custom,CNC ,10-12 cavity,hand injection mold made to your 3" swim-bait specifications.Hand pour molds w/ all of their associated caveats,fell out of popularity many years ago. Possibly one of the CNC manufacturers on this site could make you a custom,4 cavity injection mold-if you can and are willing to spend the $ for one. A true 3" swim-bait mold cannot have a thick/wide tail section in conjunction w/ a dense,wide body section ,leading into the tail for good action on the fall w/ 1/16 to 1/8 oz. weighted heads-whether the mold is hand pour or injection.The problem arises when you try to hand pour a mold made w/ the aforementioned specifications.
