UPDATE

I bought a Shoei J-Cruise 2 after they finally came back in stock.

I bought this helmet after a month of continuous research youtube etc...
I could not find any of the top helmets anywhere to try out in person.

I bought this helmet for these reasons:
Safety
High ratings
airflow
drop down dark sun screen
comfort
stability at speed (no buffeting)

I sent it back for these reasons:
It was not as comfortable as my old Schuberth C3
When the vents were open it was way too loud (annoying)
It had some buffeting

I could not find this info on youtube
I was able to install my SENA 50S
