1. At night I like flies on the dangle or across and down
2. Out of a boat I prefer to hit structure along the banks with a fly that has an extremely erratic action
3. Joe Humphreys likes flies jigging across the bottom at night in deep pools across and down
4. If fish are following / nipping / or making passes at the fly I'll drop back a trailer hook. I've never had a truely big fish crush a fly. They almost always nip at it as they investigate the fly. It is probably more curosity that anything.
