I've caught more trout on worms than I have using powerbait, although everyone swears by powerbait, for lures I'd add a couple Kastmasters and a silver super duper. You can try rigging a wolly bugger behind a casting bubble, but I've never had as much luck with flies as I have with lures and bait.
My recent experiance with the high lakes in oregon isn't that you need to have the right style or color lures for the lake, any lure will work, you just have to keep switching lures so the fish are always seeing something new.
