I have just made a new addition to the River Fly Box: The 'S Loop Nymph'.
The next time you are fishing a river or stream, turn a few submerged stones and witness the many life forms that inhabit this environment. Your eyes will usually be drawn to the bigger caddis larvae, pupae and perhaps the stone clingers. However, take a closer look and you cannot fail to see that many of the nymphs are very small and slender - and they often move very quickly and with great agility. It starts to make you realise that even your carefully tied size 14 may be a little on the large side. Therefore, it pays to carry some patterns tied in smaller sizes. For me, this is where the 'S Loop Nymph' comes into play.
