I've had a CS Voyager for a few years now and I love it. It's so light that you'll forget you have it with you and the grip isn't bad at all even when it's covered in blood.
The CS AK-47 on the other hand is the fastest opener I've ever owned and sturdy but it weighs a ton compared to all of my other folders. Totally worth it though just for the fact that it opens on the draw. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
