Keep the rod tip straight and only watch the line. Perfectly tuned lures attain correct vibration and achieve absolute maximum depth. If you troll, untuned lures will barrel roll off the bottom to the surface and will not track in river currents. The Deep Secret comes with V.M.C. wide gap, short shank, straight point bronze trebles. For super-deep cranking, keep them razor sharp to account for line stretch.
Sharp hooks are more important than anything else in deep cranking.
On most hooks, bass strikes and hard mandible bones will quickly bend the points of pre-sharpened hooks and you must establish a new point. The Deep Secret and many other Luhr Jensen modern designs are fine tools and have thin-wall body designs that produce action and vibration superior to conventional plastic crankbaits. They are the first plastic lures to equal or surpass balsa and cedar wood in performance. Even Lexan poly-carbonate, the strongest of all plastics becomes brittle at these temperatures. Just swing the lure in at rod length and manually remove weed debris.
