I have the BOA, and love it. I highly recommend their bags. The BOA is nice since it is not too thick, and can hold an amazing amount of stuff. I also have a Folee, and love it as well, amazing bags. I purchased the BOA system, and loved it so much that I got the Folee, when i needed a bit more professional bag. Note that I use the Vyper sleeve in all of them, just a bit more protection.
