IMO Russell's method of lead weights is old school thinking. Will it work, yes.
A much better mousetrap is to use Lure Jensen Deep Six divers on braided line with line counter reels. Works much better, with the only downside being the cost of the divers (Not really a big deal for most salmon fisherman).
Try it you will like it.
