Also, in some of your posts you refer to a magnetic tank bag that you like. Which one is it?
My small one is an 6L Oxford and has hung in there very well over many years.
The newest one is from Nelson Rigg and can mount magnetic and strapped - useful for me when I flip bikes. Nice feature set, life time warranty, not cheap.

I also have a very large Moto-Dry expandable I took across Canada on the CB500x. 21L expandable to 24. It weighed a ton given all my cameras etc in it.
