There are many different patterns that can imitate a crayfish, but what works best for you? Do you prefer using suggestive flys like wooly buggers, or closer imitations like Dave's crayfish or Bunnycraws? Do smaller or larger sizes worked more consistantly? I have seen imitations like the Baby-craw, but I have never used a small size crayfish pattern myself. In some of my favorite lakes that have signs of large crayfish populations, I have had good success with big, weighted brown/black buggers. I can only assume that the trout take them for a crawdad. I would like to tie a more life like pattern. Thanks for your input.
