Actually, I try not to get into the jig/fly debate. Myself, I use both gear/fly, so keep both seperate. There has been a long time built jig as described above made especially for gear fisherman. John's Jigs made them famous well over a decade ago. I'd consider it a jig, but that's because they've been jigs for quite a long time. If I put a green butt skunk tied on a salmon fly hook on the end of my bait casting rod, it's still a fly (not an unweighted fly lure). If someone wants to use one, so be it. As long as it's legal for them to use. Myself, I'll only use them on jig rods.

Onto snagging. OH YES THEY CAN SNAG QUITE WELL. Especially if you have a strike indicator on doing a swing with a fly rod. Heck, you can do it with a jig rod too if you want. The upturned eye benefits the snagger. More so if you don't use a float at all (using it on a dry flyline with no SI or a sinktip). Cast into a stacked pool and yank up (with or without a SI on). That jig is riding up, and will drive into whatever it can. Not saying everyone using them are snaggers. But you CAN snag with them. I have personally watched on a few slots where fish were stacking up (I normally fish away from them as the water recedes in tidal areas, normally only fishing at high tide when fish move). The guys will toss out to far bank and the the jig hit bottom and start hooksetting as they reel in. Usually they would hook (or shall I say snag since none were ever remotely hooked in mouth) up everywhere BUT in the mouth. Now, some were hooking in mouth, but for most part the rest were all snagging. So, just to dispell any misconceptions (since I've been fishing jigs since 1989), you can snag with them. Just depends on HOW you use them. Like I said, not everyone fishing them is snagging, just the method you use to present them that does it.
