No mate it is totally untrue, I fished with running and semi fixed leads on clips. He don't allow shelf life boilie thats correct but your will still be frozen if you put them in a polystyrene box, ask you local taclke shop as they have frozen bait delivered in them, they have freezers for your boilie. don't just look at boilies though as they are pressured fish and most of the action in during the dark hours.
