Almost all of my head molds are Do-It molds. I favor the collarless round heads and use the professional models in 1/32, 1/16, 1/8, 1/4, 3/8, 1/2. I don't alter these molds at all and I can hand cast them. I use Matzuo black nickel sickle hooks for my personal use...love the outcome. I have older models of the same heads in the everyday style of molds and have done some dinging on those. I did up a 1/32 collarless round head mold to handle #2 sickle hooks.
I have the flathead mold and the egg head mold as well. Love all of them.
