On the Nikon F soft case, it does not seem to balance correctly when carried on the shoulder, it flips backwards. A little better when carried around the neck as the stomach supports it a little. Am I missing something, or is this the way they usually fit. The strap lugs on the case seem too far forward, causing the off balance. When a strap is connected to the body lugs it balances ok. I prefer to use the half case as it gives extra grip, but this balance issue is a pain. Any help greatly appreciated.
