Yes, On the plastic bait, the insert is usually a piece of metal. These baits (with the hook slot) are intended for fishing with a tex spose hook. If you want to use a jighead just put the jighead in the normal way. The hook slot will be below the jig hook and will not interfere with the jig rigging. There are some open pour swimbaits with the hookslot molded into the mold, but once again you can rig these either way.
