imo the whole scent concept, like many things with fishing, is a marketing scheme. Water is the ultimate dilutant. And especially moving water, as it is with a lure being retrieved. There is simply no way these fish can smell anything on a lure moving through hundreds of feet of water. They are far more keyed in on their vision, hearing and lateral line senses. Do pro bass fishermen actually spray lures up before casting? No, just no. If scent is so important, we should be chumming to attract schools of bass.
Real question is why're you wearing cologne while fishing...it covers up that wonderful bass slime scent.
