Ya Hey Der – james, Your question has 2 sides to the answer
and it depends on the Crank bait or Stick bait your holding !!
If your holding a bait with a “split ring” on the eye, then you should tie “direct on to the ring”. Use the “palimor” or a “trilene” knot. You should never attach a “snap” on the ring, because you’ll be double jointing the action of the lure.
Conversely, if your holding a bait (Rapala) with just an eye (no ring). Then you tie the bait on with a “Loop Knot” or this is now the time to use a “Duo-Lock” snap. I didn’t say swivel only snaps – there again your dealing in lure action. You don’t want to do anything that thworts the lures action !!
Hope this helps.
