If it's not too late, I had a Givi on my 1100 and really liked it. The only reason I got rid of it was because I changed the seat, and that put the black trim right in my line of sight. I'm only 5'8" tall, so if you're much taller it might not work as well for you.
The best shield I tried on the 1100, though (aside from my custom-made adjustable shield) was the Laminar Combo shield, from the laminar lip folks.
