Attach sunk pattern to hook eye of the Klink or put a dropper just above the hook eye when fishing barbless.Alternative is to tie in a tippet ring on the Klink just above the bend as in previous post.Fulling Mill sell them made up for just this purpose.No need for paranoia it WILL slide off.Not every time but sure as hell when you do not need it to.Dynamic Duo | Eat, Sleep, Fishhttps://eat-sleep-fish.co.uk/content/2017/07/dynamic-duo
It isn't the knot, it's the shape of the hook's bend.
As doodry posted, get flies with micro rings at the butt then no worries over shape of hook's bend.
I was going to mention using jig hooks but JCP beat me. :thumbs:
I'll second, third, whatever the recommendation for klinks with tippet rings tied on. I've just had a week in Wales where I gave them a go - I got talked into trying them by the fishing guy in my local Orvis. #14 klinks with a ring. I loved them. I had been fishing klink'n'dink with the floating fly (usually a klink) on a shortish dropper but found the ringed klinks much more responsive and my hook up rate on rises to the klink was near enough perfect. I'm going to tie a few up when I decide what to tie the rings on with - probably extra thin wire or a v.fine bit of tippet. I don't think I quite trust thread for the job (nor can I be bothered threading it through the ring).
To tie the micro rings on I would probably use locking wire and a set of pliers and then hide the twist tail under the body of the dry. Would only need a couple of turns so it shouldnt add too much weight and there is no chance of it slipping or snapping if tied under the actual pattern of the fly.
I tie in a tippet ring at the rear of my klinks, simply threaded on to a length of mono, doubled back and lashed down tightly to the hook shank. When I reach the point where the body will start, I fold back the open ends of the loop and tie these down, but even that final stage is unnecessary (simply belt and braces).
I use 6lb mono, but the b/s is immaterial so long as it is heavier than the maximum tippet strength you will use. The weakest link, etc.
The only time I ever tie it to the bend of the hook is when winter grayling fishing when there is little chance of something coming for the dry.
I suggest tying your dry off a dropper and therefore having both your dry and nymph capable of taking fish during the trout season, even a short dropper you are wanting to fish the trio (2 nymphs off the dry).
Have used a snell/uni style knot on barbless Klink hooks which because of wraps is not probe to sliding round the bend.It worked but found other methods better for presentation,less of a fiddle and risk free.
I think any reliable knot should hold it securely?
If you don't have tippet rings you could ...
Cut the shank from a hook and tie that in for the eye, bait hooks have barbs on the shank facing towards the eye so it would tie in very securely?
