First of all, I really like my F-802. It's a great, low profile bag that can hold tons of stuff.
The only bad thing is the insert. I've bought the 720-230 insert for it, but it's impossible to place my lenshoods inside. It doens't matter if it's reversed or not: it's just too big in width. It's a 17-40L hood I'm talking about, but I've heard from other people that they've got the same problems with other hoods.
It would be great if the inserts would be a bit wider. That's my only complaint about the bag :P
Oh, by the way, It's great you guys have a forum now. Other manufacturers could learn from that...
