What is the total weight of the helmet with and without the visor? BH Composites- I believe you said you have to remove 2 cotter pins to remove the visor, correct? I was under the understanding that no tools were needed to remove the visor. And the cotter pins would wear out after a few times of taking this on and off wouldn't they? Not trying to be a skeptic at all I am very interested just curious before buying.
