One of the other posts was right -- in super light air the only thing that works is smoke. So I came up with an invention idea somebody needs to implement. Mount a punk holder up on the bridle to hold those tall, skinny incense sticks. Light the incense and stick it in the holder. It works great, but I only know because I did it by lying up on the bow and hand-holding the incense stick. Needs a holder thing. And you can pick your favorite scent!
