The coffin fly pattern using porcupine quills looks to me to be one of the more lifelike patterns available. And (hopefully) fairly easy to tie. Where do you get porcupine quills? And is there a size issue, color issue with them? I see that they are sold on e-bay by a number of people. Any recommendations there? We have gone to Potter County, Pa. for 17 years trying to catch the hatch of green drakes, fall of coffins. Hit it right maybe a total of 5 times combined. Boy, was it something!!!
