Talking to a guy working on next doors garden he mentioned that he fishes the loch. So I asked him if he uses bait or fly expecting the usual swimfeeder/maggot reply so when he said fly I asked him if he had any tips, always on the lookout for local knowledge and he told me his technique...
he uses a bubble float with a 3 fly cast on it, ok I've heard of this before and was switching off as he's not talking about "proper" fly fishing

until he finished the sentence ...with a small maggot on each fly
He reckons he catches lots like this - 36 fish in one night
It did leave me wondering why put the flies on at all? Why not just put the maggots on normal hooks?
In case you're wondering, swimfeeders and floats aren't allowed on the loch but that doesn't stop anyone from using them
