Had a lot of talk this show on musky/pike flies and the 2 schools of thought. Neither are right just different. Example, 1 is a big bulky flies with tandem feathers splayed and spun deer hair heads. These tend to be large diameter and push allot of water, but don't really swim. School 2 is more like my flies, large, but more fish like and designed to swim, easier to cast, but push less water. Examples of each at the show and talk of pros and cons of each.
