Great article Jeff, but it is like cooking, everyone has their own idea of the types of food that they like, whichis in part due to biological factors and part due to familiarity. Take simple maggots for example and colour, by far the most popular colour now is red maggots, but for many years in match circles bronze maggots ruled the roost, fishes choice or familiarity?
I confess to being a confirmed hemp & caster man myself, but when casters were unavailable I was totally convinced that turmeric flavoured & coloured maggots, were the best for roach in the winter, when there was colour in the water.
On the continent the addition of flavours and additives in groundbait is regarded almost as an art form, we have started to catch up in this country, but for many years groundbait was only seen as a carrier for loose feed, not so now.
The proliferation of carp in this country, and their willingness to exploit a new food source, has allowed experimentation to take place, with a genuine chance of success. Whereas roach, perch, tench etc are not as catholic in there taste.
