I prefer much heavier jig heads... more like 1.5 ounces up to 2 ounce. The reason for me is that I find Halibut respond to the swimbait moving more quickly on the drop. The heavier the jig, the faster it will fall to the bottom. So a quick and firm pull up, then I find they hit it on the drop. I make sure it hits bottom before popping it up off the bottom. Also, I can cast farther and cover more territory with a heavier swimbait. So just my two cents, but I've caught over 20 keepers so far this season. There are definitely better Hali jiggers than I, but I do get results with the heavier stuff.
