Here PVA bags are used to create 2 small piles of bait. One is plain 50/50 mix made in my shed (the white ones) and the other is from a major manufacturer made in thier factory (the brown ones). The experiment is to see if the fish show a preference for the shop bait but is spoilt a little as some of the baits roll down the bar toward the snag. Note, these fish are fished for all year round, and are quite spooky around boilies
