I've searched a ton, and I've narrowed it down to these two. Can't make up my mind. I put on my friend's rockgardn, and it felt great - it was a size big for me though, so I'm not sure. I don't know anybody who has a 661 around here so I can't try one of those on. Anybody have some pointers to steer me in one direction? I'm leaning more towards the rockgardn. One thing that I looked at was side protection, seems like most body armor doesn't have much of it?
