When cooler temperatures have the inshore fish slowed down a soft plastic jerkbait ( Bruiser Rad Shad pictured) can be deadly on them. Try giving the jerkbait a couple quick twitches with the rod tip to get it to dart side to side and then pause to let it mimic a crippled slowly sinking baitfish. The slowly sinking fall can be just enough to trigger a strike out of fish that wouldn't otherwise chase down a quicker moving lure.
