I use the Memphis lowers but they still let air in between them and the windshield so I have gone to a Slip Streamer clear fairing. I had one thirty years ago on a Yamaha 650 and loved it. The owner of the company just happens to ride an America. It does require moving the light bar but that's not big deal.
