I've got a Arai Quantum II with a clear shield. This is my first time with street riding. I am wondering if the clear shield will cause problems with sun glare and maybe get too hot on sunny days. I'm thinking a smoke lens or mirror finish lens may be a little better on the bright, sunny days. However, I think I'd have some problems seeing if I had to ride at night. Let me know what color of lens you prefer and what you think about the mirror finish.
