I have visited the clear water fisheries and the larger fish will often not look at the fly?

This will mainly be because the fish has already been hooked and broken or faught to the bank and released because it was deemed to small. this is an unfortunate occurance, as now that fish will take much coaxing to take again. the safest solution is to move on to smaller and smaller flies even dry flies. A stalking bug is one of the best solutions as those fish will so often refuse a larger fly but be ‘tricked’ by a smaller fly.
