Its funny when I first started to tie I heard so many times from people to not use to much dubbing at a time I got scared to use more then a slight wisp. I found I was using to little and my hares ears nympths looked like little more the a furry hook with no shape to the body it self. While it does not take much do not go to far the other way either or your fly boddies will not have any shape to them.
