I have been fly fishing and tying flies for over 30 years. Some of my favorite hooks come from Json Sweden.
Json Nymph Hook are made of thinner goods that are suitable for dry flies.
They also hook well and have the right proportion to make nice flies.
I use them for almost all my dry flies, both moths and moths.
Another of my favorites is the Json Dry Fly Hooks.
As the name suggests, they are made for dry flies with extended body. I usually use them for Baitfish imitations.
The short hook shaft and large gap make them an excellent hook for this purpose.
