I can offer only tangentially useful info: (always wanted to use that 50¢ word)
Modular: Won't wear anything else in a full helmet. I've been wearing Nolans for decades.
Fit: Yup, they grab your cheeks - that's loosen up a bit but should never get too loose.
LS2: Bought one of their lighter weight models for summer city riding. Seems to be good quality.
I appreciate your insights ... tangential as they may be. Every little piece of information adds to my decision making process. Stay Safe!
