On the subject of twist direction,I was curious about this also so I did an experiment with pieces of old fly line so I could easily watch what was happening. If you are looking from the bobbin towards the hook and you are right-handed you should twist ccw so that the subsequent wrapping will add more twists and not unwind what you've done. Obviously this does not count if you are using a rotary vise. Try the test.
