I just picked this up for my new (to me) 300 2.8; it'd be an extremely useful feature if the wrap-around strap, at least on the side that doesn't have the monopod velcro, was loose like they are on the satchels (F-802, et. al.) so you could add a couple of F-901 or F-902 pockets for a little extra gear like a smaller lens and/or a flash. A small pocket in the top flap would also be handy; I keep $0.99 throwaway ponchos in all my bags against unexpected rain. And it may be just me, but I really prefer the sand color for my bags rather than black.
