I got a Wunderlich touring windshield. It's made specifically for the 310R, so there is no adjusting to do when you install it, which is not difficult. It's extremely solid when it's bolted on, more so than any other windshield I've seen. Very high quality. It gives me good protection when riding, with no buffeting. Yes, it costs more than other windshields that fit a 310, but in my opinion it's worth it.
