Grand Slam Series lures have a 4" head, with a 1 3/8" diameter, a bullet front, and a 9" silicone skirt. Each TKO Grand Slam lure has a 3D scale pattern in the lure head. These lures troll at 4-18 knots. The faster the troll, the deeper the dive. Plan your next Grand Slam with these lures! Grand Slam Series lures are available in seven scale pattern colors: Chartreuse, Purple, Light Blue, Green, Orange, Pink, Red. For information about which color of lure to use at what time of day, please read my Time & Lure Color page.
