I must say that the new slick shiner is poised to be quite a versatile bait in the arsenal. Shoots smooth and the 8 cavities is a dream. Now I just need to get a retro fit for dual injection. Well played Do It, well played.
Don't know about the fish, but the Magic Craw Blue attracts me.
To me this looks like some green pumpkin plastic with .015 gold flake, .035/.040 copper flake and .035/.40 moss green flake just based on the picture.
I'm thinking a 4/0 hook should be the one to pair with the 4G4... my understanding is that the last digit (on any of the Herter's jig molds) was related to size in eighths of an ounce, so a 4G1 would be 1/8oz, a 4G2 would be 1/4oz and so on. And the rule of thumb would be to use a corresponding step in hook size with each, so 1/0 hook with 1/8oz, 2/0 hook with 1/4oz, and so on.
A quick internet search will turn up lots of pictures with various series molds side by side, confirming the relative size differences, but I only found one source (worthpoint) referencing the hook correlation.
