What is everyone's opinion on snap hooks for fly to tippet?
I ask because I have young boys who are always needing my help when changing flys (though their knots are slowly improving) then I discovered these things at my local tackle shop and absolutely love em.
I saw three immediate advantages: 1. you can change flys in seconds (i grasp the bottom of the hook with locking forceps then snap on and off flys), 2. the fly seems to swim more natural, and 3. i'm not shortening the tippet with every change
I dont know how many different kinds are out there, but the ones i'm using are really small (add virtually no weight to the fly and barely big enough for the hook eye)
What are the negatives?
