These bright yellow hookbaits are infused with two of carp angling's most proven additives, and after all, who's Fluoro Range would be complete without a good old Pineapple & N 'Butyric Hookbait?The esters from the pineapple flavour work synergistically with the n 'butyric acid creating a time old attractor package that carp simply can 't resist. N 'butyric acid is a carboxylic acid with a short carbon chain, in simple terms it means it is incredibly soluble in all water temperatures and carp can detect it at even the lowest of levels.The carefully balanced, needle friendly wafters will slowly sink under the weight of the hook. For anyone unfamiliar with the principal, the Pineapple & N 'Butyric Wafters perfectly counteract the weight of your rig, leaving a critically balanced bait that will fool even the wariest of carp.These can be a great way of scratching out a bite on an otherwise unproductive day, the perfect emergency yellow hookbaits. A proven winner and winter favourite, these are great fished as singles of over a scattering of boilies.
