I am old enough to remember when Hemp was banned by many angling clubs and associations as it was believed that the fish became addicted to it ! Other clubs used to ban bloodworm and jokers as it gave those who could get them an unfair advantage in fishing matches. As anglers we are always seeking that magic bait or groundbait that the fish find irresistible . I was in the tackle shop the other day and there was literally dozens of different flavoured groundbaits , pellets , boilies plus lots of glugs and additives , do they all work ? I'm of the mind that if an angler believes a particular bait or additive gives them an edge then it becomes a self fulfilling prophecy . I am no different from everyone else and think that certain baits can produce better results , ultimately though we never really know as there are so many other factors influencing whether the fish take our bait or are attracted by our groundbait ., I still swear by Garlic Spam , and I still have a bottle of glug called ' minging fish ' and it certainly does ming , but I still give it a try now and again . The only bait I have ever used that seemed to drive fish , particularly chub in to a feeding frenzy was wasp grub / wasp cake , hard to get hold of but they certainly seem to throw caution to the wind whenever I use it , never caught a barbel on it though ....
