Sutherland is a good Cutthroat lake, I would try a small brass, or silver spoon (1 1/2") Troll fairly fast and hit shorelines and don't be afraid to run right along stumps and logs. Zig zag, don't go in a line for any length of time. Watch the lake temp too, if you have a thermometer, you want to be fishing between around 47-57 degrees water temp, colder or warmer, trout go sluggish for trolling.
