I'm not going down to Fla until march but last year I realized that the Punta Gorda canals are full of Jack Crevalle! They ram baitfish like Mullet, Silversides, and Glass Minnows (Anchovies) up against the surface/sea walls, creating noise that brings people out of their houses! 
So how do you catch them? Next year i'm gonna spend more time working lures in the middle of the canal to pick up a cruising Jack, and trolling for Jacks/Snook/Goliath Grouper (on the way to my Stingray spot at least
)
The guide we went with used a 6 inch Yo Zuri Crystal Minnow in Redhead and I hauled in a Barracuda! Usually the Jacks frenzy across the canal. I want to try a plug attached to a line with a 6 oz sinker so I can cast. I know that lighter line would make for better casting, but Jacks can push 20 pounds, have unlimited stamina, and can easily break me off on a cement dock or an oyster bed so I'm gonna use 50 lb braid and a wire leader.
