My only suggestion is to incorporate more configurable 'felt-side' velcro strips in the bag to allow for user-sized compartment options. Otherwise, this is an excellent upgrade from my Velocity Series bag.
I have carried a Tamrac 4.2 bag for at least 5 years. It is a very well laid out and comfortable bag. I needed slightly more capacity, so I bought the 6.2. Same great lay out with more room. The chocolate color is great. The canvas is so much more comfortable in the heat than the hard nylon bags, and it shapes a bit around your body. thank you.
