Hi. I'm new to motorcycling and LOVING my Vulcan 900 Custom SE. I'm adding my first windshield for occasional 2-3 hour long trips. Comfort on the highway (65 -70 mph) is more important than style but I definitely favor the look of sport shields. I'm 5'11" with a long torso and don't want one that just directs air from my body to my head. I'm considering the National Cycle Street Screen EX (18" high), or the Memphis Shades Big Shot 20", or Alley Cat 18" high. Any actual experience with these, especially from tall people, like myself? FYI - I'll probably order something by July 6th.
