Hi,
I put aero screens on my 2b, you do get the wind in your face and on a motorway it can be quiet severe , so i always keep a helmet in the car use it on longer faster runs and don,t on the shorter runs. mainly as i don,t wish to be shot by any debris.
Having rode bikes for 19years i,m use to helmets its no different in the car to the bike.
I prefer aero screens i,m in a tin top day in day out so the more different the better at weekends if you are anywhere near come out in mine and see what you think. Svc supplied mine.
