I consider PC a wonder material yet I went back to 1.7 AR coated glass (higher than that it's a bit overkill unless you really need it IMO). It's crisper, actually cheaper, heat resistant and virtually scratch proof if you clean it properly. It's heavier but I'm not going back to finding pinpricks after bouts of wind and all the extra care. The thing about glass is that it can shatter upon impact, plastic lenses won't but basically get ruined all the same in my experience.
