I have hooked fish on cochy-y-bondu's, not sure if I spelt that right, I have also hooked fish on blackcrunchers and doobry's. Never seen much if any fly life apart from the odd damsel and caddis, most of the insects I would imagine are terrestrial. Also rekon brown muddlers would be worth a try as I have seen alot of tiny fish in the margins that I assume are Parr and if they are then I am sure the larger brownies would have one for supper.
As for the best area's well I ceratinly have not found them yet, It has always been blowing a hooly when I have been so the wind usually dictates where I am gonna fish.
Crowdy I have only fished once, I only saw the odd tiny wildie sipping flies too small to imitate.I tried my smallest flies but never had a bite

ahem sorry I meant pull

.....I did speak to an older bloke who I asked if there were any trout in here and he relplied that there were not any fish at all in Crowdy. I thought this a little strange as he was standing there telling me this whilst holding a rigged up fly rod in his hand ? He then realised the folly of his statement and told me that he was up here to practise his casting ??. I said no more and left him to it with a wry smile on my face.
Well its blowing a hoolie again so see how my first go a temple goes and the maybe off to Colliford after.
