It was my pleasure to fish with those guys the other day... I like to check in on the Fly Talk crowd now and then, and see who is bringing game to the conversation. Bottom line: Mr. Metzger can flat-out fly fish (so can Mark). Andrew taught me a good lesson worth sharing... rather than using a yarn or bobber strike indicator, he connects his fly line to a leader with a strand of red amnesia line. This serves two purposes: First, the stiff amnesia line helps him turn the line over easier when roll casting or punching casts into the wind; second, it serves as a de-facto indicator, without a gaudy profile. It also slices through the current with less drag on the line. Watch the red line wobble or stall, set the hook, and quite often you'll find yourself on a fish.
