Ok, Im not a weight weenie, but I also don't want to carry around an extra wheels worth of weight. I guess my question is how much of a difference does 200g really make? 200 grams is less than a half pound. I weigh #320. A half pound of wheel that would be basically indestructable doesn't seem like I would even notice it except maybe the first time I have to carry it up the stairs.

if this means I'd never have to tension or true my wheel for years, where the hell do I sign up? especially at $70 per wheel?
