iv been working on deck designs for partical scooters for the past month or so, and im finally happy with one design. it weighs in at around 3 1/2 pounds including the headtube. I was wondering if you guys think this is too heavy, i could make it lighter, but at the same time i would be making it weaker. so the question is weather you prefer strength or weight. oh and what is the internal diameter of a head tube? i measured but i want to be sure. Thanks
