Maybe if you can find a buddy that has one installed and see if you like it. From what I've read, my helmet (Shoei X11) seems to be pretty susceptible to turbulence in the chin area, and I definitely noticed it. Earplugs were a must for 50+ mph riding after installing the small Yamaha screen for me.
Helmets are different. People are different (sizes), so your mileage may vary.
I'd bet money that, screen or no screen, the new Max (if it had any time in the wind tunnel) will be much quieter from a turbulence standpoint than the current VMax.
