i, on the other hand, would not.  when i used one for a day skiing, i hated it.  it was wayyy too big and bulky.  it did it's job really well, but i don't see how it would be a ton better than the smaller braces.  i usually use a donjoy, and it's one of my favorites.  it's light and it's small and supportive; nothing fancy, it does it's job.  i just had my acl replaced and i need a new brace, though.  i'm looking into breg.  their active brace, or whatever you call it, actually has the metal suport that sits off of your skin about 5 mm; there's padding everywhere else.  kinda hard to explain, but they look to be nice a light, and i've personally heard nothing but good about them.  I can't attest to CTI, but i've heard from a few dudes who've used most braces that they're wayyyy over-rated.  hope that helps?  Donjoy, and look into breg.
