Fred's choice is one major bag which is normally meant for 600/800 lenses, plus it is $100 more expensive than Tenba LL400. I guess, Fred is a young buck who doesn't mind carrying an oversized bag for the benefit of having in it his 500 II with the hood mounted in the shooting position.
Based on a couple of Kinesis bags I have owned, I think Tenba's LL bags are better made, and that is why I currently have six Tenba LL bags in continuous use (for lens storage at home as well). Although I do have two Tenba LL600 bags which are similar in size to Kinesis L611, I certainly do not carry any shorter lenses in them, only 600 and 800 because those two lenses. even with their hoods mounted backwards, do not fit into anything smaller. Now, I still haven't seen a dedicated long lens/camera bag which would allow you carry 600/800 with the hood mounted in the shooting position, but I have no doubt that such bags and backpacks do exist.
