Start by using 90- to 130-pound fluorocarbon for your shock leader. This material can only be 12 inches long, including knot lengths, if you are following IGFA rules. Attach one of the hooks using a 1.2-mm crimp to the end of the shock leader, leaving enough of a loop to allow the hook to swing freely. Cut a piece of 1.5-mm plastic-coated chafing gear to the length you want your hooks spaced apart and slide onto the leader (optional). Thread the forward hook onto the shock leader and make a loop in the leader with the forward hook eye inside the loop. Slide a 1.7-mm crimp over the loop and main line and crimp tightly, again leaving enough of a loop to allow the hook to swing freely. Now slide your popper fly down over the hook-set and attach to your tippet length in your preferred manner.
