Fran Betters was a great and inovative fly tyer. I was chatting with a guy that fishes the Adirondaks quite often and he told me that he would always stop at Fran's shop for a coupla flies. BUT, he said that after one trout, the fly would come apart. I laughed, because my buddy always had the same complaint about Fran's flies So I always use head cement when I tie a fly.
Adios, Philip
