I was planning on buying an AP pack but haven't been able to visit an O store since they've been released, so I'm hoping the O Review can help me here. I love my Icon pack and it's served me well for years, but it’s beginning to show its age. So, just how large is the AP pack when compared to an Icon 1.0 pack? I read the dimension on Zappos and they list it as smaller, but I thought it looked larger, if not the same on their model. Not sure, maybe I'm going crazy. My other question deals with the detachable areas; just how many of these areas are capable of being removed. Thanks for the help!
