A lot has been brought up regarding the quality of the tools and materials found in a fly tying kit. This has led me to question the quality of flies in a fly assortment. I was thinking about buying one, but now I wonder. At Orvis, if I but individual flies,every fly is 2 bucks and they appear to be of good quality and they really look nice. Should I keep buying this way(which is more expensive) or do the assortments include quality flies?
