If there was one fly and one method that worked all the time, that's what everyone would be doing. Fly fishing is about making adjustments, regardless of the style/method. I don't know if that's what it's all about, but that's one aspect. Everyone here has presented a different way to solve the same problem. The reason is they've all found a way that works for them. That's what makes it an interesting game. Good luck on the deep hole!
