I'm partial to the Snake since the camo index is high, but I switch to Spirit when I'm running in to CQC somebody or hold them up and put them to sleep. Unfortunately, the Spirit has low camo index, which is why I don't use it frequently.
I also love the look of the Sneaking Suit, plus the defense and stamina boost it brings. But once again, it compromises me with a low camo index. --- http://tinyurl.com/ckb9ykw http://www.gamerhandles.com/sig/Durango.jpg
