Do scents attract predator fish, YES! And bass included both small and largemouth. I design soft plastics and have recently finished extensively testing a new prey scent that actually had largemouth following the scent trail to the boat. I tried testing several times with one of my staff in heavily fished waters and it showed me enough to take it to the next level. I fished the front of the boat in all cases with the same color and bait as staff member on each occasion and he was using the scent and I wasn't. He consistently tied or beat me in numbers and he had never even come close to doing this before. We were fishing Texas rigged craws on each outing and he would spray a small amount of the oil base scent on bait every 3rd or 4th cast. We then went to three different small lakes that have little or no fishing pressure. It was then that I saw the big effect. Identical situation as before but on these test we noticed that when we stopped to re tie etc. he would cast behind the boat in areas we had already covered and his strike percentage increased exponentially. The bass were actually following the scent trail that he had left. Did I cast back there and get in on the frenzies, of course I did, who wouldn't and I caught them just like he did until we gave em all sore mouths. I have since started cooking the scent into my baits and it works great but spraying has the edge, which apparently leaves more of a scent trail on the bottom structure ie weeds, timber, rocks etc. All of these test were done while fishing down bank structure and as most of us front enders do, I covered it closely. This scent isn't available as of yet but will be sometime in the near future. It is my opinion that many scents on the market are equally as effective but I don't get paid to test other companies scents. All I know is for a fact, SCENTS WORK! And not just water based scents
