During sailfish season in south Florida, crews reach for the dredge teaser to lure sails into the spread. Some of these three-tiered dredges hold over 60 split-tail mullet to simulate a ball of bait moving behind the boat. Captains who mark bait deep will even stop or slow down to let the dredges fall in the water column in an effort to drag some sails up from the depths. This tactic works like gangbusters, and guys like Glenn Cameron on Floridian have made a living whipping folks in tournaments using this technique.

Since most of the boats are pulling dredges and dead ballyhoo, they rarely exceed 4 or 5 knots when trolling to keep their baits from falling apart. And while these speeds make a split-tailed mullet swim like its alive, artificial dredges sometimes need a little extra flash at 4 knots to keep them animated.
 
Lately, I've started to pump up my dredges with the addition of some mylar strip baits and spinner blades like the ones used on bass lures.
 
To make my spinner additions I start with a 10-inch section of 150-pound fluorocarbon leader. Crimp a 60-pound ball-bearing snap swivel to one end and slide a round bead down the leader to the swivel. Now thread on a half-ounce Mylar Bluewater Candy lure followed by a glow bead and nine or 10 small round beads for spacers. 
 
Snap another 60-pound snap swivel to a brass spinner blade of your choice, and slide the swivel end over the fluorocarbon. Finish this end of the rig with one more spacer bead and a small loop.
 
At the other end of the fluorocarbon, where you attached the first swivel, clip on a Calcutta Strip bait by folding over the end of the strip, punching a hole through it and passing the swivel clip through the resulting fold. I like to use a healthy dose of Zap-A-Gap to make sure the fold doesn't come apart.

You can now attach the entire rig to the tail end of any dredge arrangement to add an extra bit of flash to your school of bait.
