Introducing Spotsticker Baits's Casting Jig.
Impressions: What makes a specific jig a casting jig versus a flipping jig versus a swimming jig, etc? Really it's all in the hook. Nothing is stopping you from using any type of jig with any type of head for any specific purpose, but the type of hook that is used to build that jig is there with consideration of what type of tackle you will be using all in an effort to help make that task of setting the hook easier.
Essentially, the lighter the tackle you will be using, the thinner wire hook you can use in the jig. The thinner wire hook you use in a jig means easier hook penetration, but if you use a thin wire hook with heavy tackle, you run the risk of having that hook straighten out.
Casting Jig is
a pseudonym for all purpose.
With that being said, flipping hooks use heavy gauge wired hooks because the assumption is you're using very powerful rods with heavy pound test line so you can exert a lot of pressure on the fish to pull them out of cover.
A thin wire hook will not cut it in these situations. Conversely with a swimming jig, where the assumption is, you're using lighter line and tackle so as not to spook the fish with line diameter, a thinner wire hook will allow you the hook penetration you may otherwise not be able to achieve with a heavy gauged hook on light tackle.
