I was able to personally see and discuss with BNR what he's brought up in this thread.
Irrespective of the legality or not of the equipment in question here, the discussion, as far as head color, width, color, etc is everything I hate being fashion police. Safety issues I can buy (and I'm not sure it applies here). But color, width, height, length, logo...in practice, we shouldn't be responsible for IMO.
