I have some lead weights to get me down deep. 4 oz. to 12 oz. it says on them. Can I attach them to my 40" leaders where the swivel meets the line or should I run a 3 Way swivel before that to NOT spook the fish? I was thinking just to hook it on my mono leaders since they are the longest ones. Is this correct? I mean where the line meets the leader???? thanks Fish N ski. (boy do I need some schooling)
