These typically come/people use, the 6" RAM Arm with these. Has anyone used the 3" or 2" arm instead? Thoughts/pictures? I am thinking of getting some of these and want to position them low to get them out of the path of airflow towards my head and for looks also and when I see the 6" arm mirrors position low they are sticking out on the side more than I would like. I am not a particularly wide person and don't foresee any reward vision issues placing this lower and out (with the shorter arms).
