I personally like the Lowepro Flipside, for me, it works as it holds all of my gear. If I need to change a lens, I take my arms out of the staps, while the bottom straps are still connect around my waist I swing the back around and open it up to reveal my gear- it's like having a table top right there. They have a demonstration video on it as well: http://products.lowepro.com/product/...AW,2116,14.htm

Edit: Looks like I'm too late
