Try it and see, that's really the only way to know if it's going to do anything for you. I have lip stops on most of my trumpets but not on any of my wing bones. For me it's mostly the aesthetics, I think the stops help balance the overall appearance of the trumpets, but the bones look better to me without. In my opinion the lip stops are a little more functional on the trumpets also, I don't ever have any trouble maintaining positioning with the larger/flatter mouthpiece on a wing bone, but I find I sometimes lose track of the narrow, perfectly round trumpet mouthpieces when they are on my lip.
