Werner, jigging (real jigging, no bobbers allowed) can be an awesome technique to catch salmon, but unless I'm marking alot of fish and or bait, I don't make it my first choice, if there is bait around and you have the technique down, you will smoke trollers and hold your own with moochers.
As for technique, 1st, I use a 71/2ft. 1pc. rod, its a custom made rod very similar to a Lami Puget Jigger, with a Penn Mag 10 reel (direct drive) so I can drop the jig quick if I miss a strike. 2nd, I like to lift the rod about 5-6ft fairly quickly then drop the tip just fast enough to let slack in the line so that the jig flutters as it drops, the drop/flutter is when most strikes occur. 3rd, get rid of all trebles and go with a good quality siwash. Last, for kings If I had to pick 1 jig it would be a green and white Pt. Wilson Dart, the bigger the better, for bottomfish, any jig as long as its white.
As for the resort owner recommendation of jigs, keep in mind if fish and or bait is present you'll do fine with the jigs, if things are slow or spotty have herring on hand. Back in 89 my dad and uncle and I went to fish Ucluelet (Canadian Princess resort) the only thing they supply are jigs (only 1 choice of jigs at that) we brought our own herring and the 3 of us probably caught at least half of the boat limit. Hope this helps a little, good luck.
