[Leica] Any opinions from users of sling type camera bags?

[Frank Filippone]

Looking to somerhing small and easy to get into. The shoulder bags I have used are putting a strain on my back. Maybe the sling bag would take off the asymetrical strain?
If you have tried one and have a specific recommendation, Inwould be much appreciative if you would share your opinions 
Note that small bacKpacks do not offer easy access to contents, so not interested in them.
