I have 300 V Style heads from Cast Industries in 1/2, and 3/8, along with some 3/4 and 1 oz in the same V style mold. They gave me .32 in all sizes. Some were ordered direct. Some i ordered through lure parts online. Maybe it just depends on the mold you are requesting. My point is you can always call and ask. However the super stainless wire is the ticket if you want the best vibration IMHO.
