Not sure if it is what you are looking for. Also there larva mold is a straight hook. If you can find a mold that like the larva mold you can always use plumbers putty to shape the round head if need be. All you do is put plumbers putty in mold where you dont want the lead to go. It will last a while and wont have to worry about it melting. This also works with making a no collar jig from a mold that has a collar.
