i tie a lot of flies for bluegill,and redear(chinks) ,the most productive flies for me have been the ones with rubber legs.
why these fish like the legie flies is a mistery to me ,just a simple sinking spider with lots of legs or a dragon nymph with rubber legs will out produce almost any file i tie.
although both blue gill and redear can be picky at times the legs have it.
i have often wondered why ?
