5'8, love it. Either full down (normal day-to-day riding with wind on lid but no buffetting) or full up (motorway miles, fully protected), it's very good. Only issue is that when it's full up I'm looking through it, and the curved shape does change the visable perspective, so it's not really any use fully raised for scratching.
Everyone will be different, but IMHO it really does give you a lot more options.
