The No-Knot Fas-Snaps rock Bosman I have been using them for many years now, back in the day you could only find them in the Fly section at your local bait shop.
There are some that don’t like the way the gill pills hang from them (or some other baits) but I have experienced just the opposite. Everyone has a preference in there presentation
For vertical they cannot be beat. Without a knot directly to the vertical jig or horizontal for that matter, your bait will pick up a ton more action because it is not hindered by being directly tied to the line.
The other big bonus to the snaps…..on them very cold days a lot of guys get lazy and do not change up jigs as often as they should. With the Fas Snap I can change out a jig and have the hands back into protection in the matter of seconds while hole hopping. Most of the time it takes longer for me to decide what jig to use next than it takes to change them out
Good luck on the ice and welcome to IDO
