maybe, but then its not just the flavour, its the oils, liquids and the soluble ingredients in the bait that do the attracting, so if, for example, everyones using high-oil baits, try a low oil one, or you soak the bait in the lake overnight to get rid of the possible danger signals. thats why i stick a little "washing tablet" bag of baits in the margin overnight. that way IF i catch a fish in the morning, i can put an "identical" freebie out, rather than a "fresh" bait over the top of a load of old ones.
