Birdman, first understand I'm new to this whole casting baits thing and am looking for projects to get me started.
I haven't decided whether to do a hard or soft version. If I go with a hard bait, I'll probably use something like Featherlite or Smooth-on's heavier product. If I go for a soft bait, I'll use Plastisol or something similar.
Either would most likely be a two part mold.
Here's a snapshot of the item I'm trying to cast.
