In the winter, I use larger jigs up to an 1/8. Summer is a 1/32 with clear and low water in the PNW, at least where I go. I was tying up a few Kilowatts over the weekend. See Dec 07 issue of Fly Fisherman. Not really a jig but tied on a jig hook.
If the price was the same, I would love it if all hooks were barbless since I have to pinch them all anyway. I had a bunch of salmon hooks break last year. Makes you wonder if it was from pinching the barb or just a bad batch of hooks.
