My buddy swears that you have to fish tricos on 7X because the fish know (can see it). I seem to have as many takes with the 6X I use. We're both happy so I guess that's all that counts. As I was learning to fly fish my mentor only went as small as 6X for any fishing. I think many of our beliefs come from the people who taught us. There are no absolutes in fly fishing and I think we sometimes for that.

John, a buddy and I use orange sleeve indicators on our leaders. Not as floats just to help see them. We had so many fish trying to eat the orange indicators that he started tying beetles out of orange foam. They work like a charm when the fish are looking up during the warmer months. Don't know if it's the orange color, but it suredoesn't hurt.
