My guest this week is the great George Daniel [42:00], who is always pushing the envelope, evolving and experimenting.  He tells us why he uses a 10-foot fly rod for nearly all of his trout fishing, even in smaller streams and he also introduces a new nymphing technique he has been experimenting with.   In the Fly Box this week, we have a great variety of questions and tips, including: Can I use a poly leader in salt water for stripers? Why do I find fewer and smaller fish in low water conditions later in the season? How often do you find yourself adjusting indicator depth in medium and large rivers? What should I do with the reject flies from my tying bench? Is a bow-and-arrow cast stealthier than a roll cast in small streams? I see large crayfish in a stream.  Why don't I see smaller crayfish? Are fiberglass rods more sensitive than graphite rods? Do creek chubs compete with brown trout? What can I do to keep the wings on my parachute flies at 90 degrees once I start fishing them? I found I could double haul better with some Orvis rods I tried than with entry level rods I have.  Is it simply the difference between a premium rod and my current lower level rods? I keep breaking off coho salmon.  What could I be doing wrong? Can I fish egg and worm patterns and streamers with my 7-foot, 4-weight rod? A tip from a listener—if you want to find out where trout live in a particular river, observe them from a bridge. Is there an organization devoted specifically to smallmouth bass?
