WillCad, loved what you did to the innards. Especially the last photo set.
Looks just like the lowepro shoulder I have. Certainly not for the faint of heart The idea of adding the U hooks for shoulder straps is fantastic. However, how did the weight distribution feel on your back?

I am an amateur photographer in addition to my day job. After trying various bags, I settled on the Crumpler (I use the 5 million dollar bag) for ease of access and weight distribution.
