New to using spinners and lures. I always fly fished or bait for trout. Want to get into using lures. Do most of you use a duolock and a bout 18 inches of leader with a swivels. I have heard use a split ring with a swivels connected to split ring with 18 inches leader.also heard 18 inches leader with duolock also swivels leader and just a loop knot tied to lure or spinner.does it really matter were you use a swivels up the line with a leader or swivels attached to your lure or spinner?
