I'm using the National Cycle Chopped Tinted SwitchBlade. Easy on / easy off. Bit of a bugger to get installed in the first place, but I like it. If you're taller, you can use the regular Switchblade, not the Chopped one.
For the America, installation should be a bit easier because I don't think you'll have clearance issues with the turn signals. YMMV.
I believe the difference in the older versus newer bikes is the straight versus tapered shrouds.
