in order to avoid the cost of snap swivels, i put mine right on the umbrella arms and use a uni knot to toe the line to the leader. I figure i save a few a bucks in snap swivels each trip. My son in law barry however, he insists on using snap swivels and i make him bring his own when he comes out with me.
ive done both and i like swivles better. They seem to have better action and last longer that way. While we are on the subject of teasers...I saw a guy last year that had chart. rat-l-traps on his umbrella along with shads....anyone ever done this?
