A Honda Tall with vent came on the bike when I got it. I liked it. I changed to a Mstad with a 11 inch shield. I also like it. I see a little further over the Mstad than the Honda Tall, and it has similar protection. If you opt for a non Mstad shield, make sure you get a shield with a vent. The vent, aimed at the top of your helmet, will increase airflow and therefore keep the pressure high enough from allowing a low pressure area to form and suck in turbulent air around your helmet.
