The Ty-Rite can be attached to a zinger, and still swivel. Spinning it in your finger results in a very quick number of twists in the line. I only have the Junior model, and it holds everything from #24 to #14 flies, and holds them tight
. The hooked wire comes out when the plunger is depressed, and retracts tightly until released. It's much lighter than forceps, and there's zero chance of an accidental opening. I think it was a brilliant idea.
I've had one threader break during the past two years. It might have been as a result of using a heavy leader with a small eye/small fly, but the wire split
at the very tip. I wouldn't recommend threading 4X tippet on a #20 fly, but other than that, they've worked fine for me. I would love to trade all of my small eye hooks for large eye hooks, but don't see how that'd work. Guess I'll tie them all up, and aim for bushes and trees. That'll give me the excuse to buy all large eye #18 hooks.
I have one of the magnetic threaders, but have only tried it at home. It's in my large gear bag, but has never made it to my vest. I blame the Ty-Rite for
that. The Ty-Rite allows me to steady my hand enough to thread a #18 BWO in seconds, and then spin the knot.
