For me, the 2-Up shield was the most comfortable. I’m a big, as in wide, guy. When I sit behind a windshield I want one that provides plenty of protection, which the 2-Up certainly did. Optically, it was very good, and buffeting wasn’t an issue. If it were my dough, this one would be my first choice. I wasn’t as thrilled with the Shorty. It was a bit small for my taste, hence the name, I suppose. Around town I could live with the windblast, but unless you’re vertically challenged or more concerned with form than function, my recommendation would be to try the 2-Up first. It’s certainly easy enough to change if you don’t like it.
