How#2

I always use "Snap Hooks" (via Netcraft) on all my jigs when fishing. Gives them a much freer action in the water. The DuoLock variety is a much heavier wire than those offered by Netcraft. The ones here (from Netcraft) were designed for attaching to flies to the leaders, for the fly fishermen, so they are ultra thin, springy wire and not very visible, in my opinion. I use the mid-size (#2) for 1/32 - 1/16 oz. jigs. Never had an adverse affect on my catch ratio, with others in the boat not using them. So, it works for me! :)

I used to use fast snaps when fishing a jig on a float. Bill Dance was using it on one of his crappie shows and said it kept the lure laying horizontal in the water.
Now I use a fluorocarbon knot and pull the knot back towards the point of the hook. You can find out how to tie it on Youtube. Look for best fluorocarbon knot. It's more difficult to tie but to me it's worth it.

I use the snaps when searching for fish with crankbaits, only because I can switch much faster that way. For everything else I tie directly to the lure.
