I have had problems tying this knot to small hooks because of the eye of the hook is a bit small...
There is a difference between a circle and a J hook.
On a circle the line must pass through the eye coming out on the hook side, this completes the circle, the way it was done there will defeat the purpose making for many missed hook ups.
To do a snell on a J hook, the hook must have a down eye for the line to pass through to keep it straight.
