Q. When the water is calm on the flats, I find that a leader of 12 feet or longer is necessary to prevent spooking fish like bonefish and permit. For years I've used either a nail knot or a whipped loop to connect the fly line to the butt section of my leader. To land a fish with a longer leader, some of the butt section must be brought inside the rod guides, and if a fish surges away, the nail knot or whipped loop sometimes catches on the snake guides. I've lost two big bones because of this very problem. Do you have any suggestions on how I can avoid breaking my tippet while landing fish?"
