you can always scale up. i do not miss varibright btw. don't get me wrong, it is gorgeous and amazing, but if your prime goal is delving into max, brightness will be the least of your issues for a very long time.
all that said, i cannot rec highly enough buying new stuff straight from source as you can't support a better business.
i just have an attachment to the old black silicone and weight/feel/size as well as how the button action has aged so incredibly (hope they don't fail).
