Over all these years of fishing top waters, I put a turquoises stripe on all my spooks as well as any top water. As the bait is twitched it dips under the water and turns a little sideways.
Of course some like the spook does this much more defined than other baits. None the less even Torpedos will make that side dip. This flashes a ghost image under the surface that big bass cannot resist.
The stripe painted on the side has holographic glitter of 5 colors representing the scales of bait fish. I have a formula for this and add it to the paint. This makes all the difference in getting the Big Bite to take place. I am not saying it will double your big bass size on the torpedo; but you will see a remarkable difference.
I had some crank baits painted to match my tournament spooks and will be testing them in Mexico this March. They look great and I expect them to produce the same results on big fish.
