Using the small wet flies and dry flies as a starting point it is clear the size of the fish attracted to any given pattern increases with the size of the fly. The "Wall of Fame" represents a history of Montana Fly Fishing during the catchem and eatem days of the 1950's and 1960's. Hardly anybody kills a four poind fish anymore, and if they do they don't bring it in to put on the wall. The figures above become even more impressive when you consider most Montana fly fishermen were fishing with dry flies Montana Nymphs or Woolly Worms in those days. A minority of streamer-fly fishermen were catching a disproportionate number of large trout. They still are.
