I don’t see any harm in at least,trying some of the many and now vast flavourings,that are out there.If you feel that some additive is assisting,and you can moniter your results,then go ahead.There does seem to be enougth evidence to back up most claims,after all,most of your groundbaits contain alot of additives,and we all have our favorites !!..if people wish to continue to bury their heads in the sand with regards to these products then, so be it,let an individual’s results speak for themselves,Most match men are increasingly,looking at what the carp men use,and adopting their proven baits and various rigs,so give it a go…you’ll never know intil you try !!
