From the Manufacturer: These 10" Lures are killing Dorado, Tuna, Marlin and Wahoo from the Gulf, Caribbean to the Pacific and the Atlantic Ocean these little morsels of bait are bringing in some serious big game fish. Striped Marlin and sailfish really seem to be taking a liking to the way the fish kind of jumps and dives in the water, but dorado and wahoo certainly are not passing these little Phoenix Lures up. We recommend a troll speed of 6-9 knots on these truly amazing marlin, dorado, and tuna lures. It seems these lures are taking over many spreads from traditional resin head lures.
