Maybe I'm too fussy, but I think the snap/swivel may add too much flash or size to the jig. I always tie directly to the hook, and in most situations, I will outfish someone that uses a swivel. That being said, a snap/swivel does work to catch eyes too (sometimes the eyes want some flash....go figure!). So I dunno. When I was a small kid I always used a snap swivel, so I could change hooks easier, and caught eyes. Now I just cut the line and retie, takes no time at all.
