it isn't that unfair when you think about it - the reason why these 5 or 6 guys get to run such prototypes when us mere mortals don't is that they've proven countless times that they're above the rest to start with... so, B4.1 or C4.1 they'd still whoop your rear anyway
Now I'd rather have them test it fully before releasing it to the public anyway than push a lemon on the market (DNX408 anyone?)
