Scents?

[maddawg]

You make a good point with the spitting. I've been know to do that. However I didn't really stop to think if it adds scent to the fly. I had just heard if your trying to fish an emerger type patter without weight, syliva will break the water tension and put your fly where you want it.

Here's a good question I'd like to ask the purist dry fly fishermen, why do they feel they lower their standards when they nymph fish?
