That is a great help to see the pictures - many thanks Tripletom!
I can certainly appreciate the quality of Kriega products, however, I do find some of their stuff a bit 'fussy'?
If I might make a recommendation for an alternative tank bag that is quick release etc. then have a look at the Wolfman Enduro Tank Bag:
www.wolfmanluggage.com/
and the UK distributor:

I'm not suggesting this
instead of the Kriega, but it is certainly an option, especially for those a little more cash-strapped...

btw. they also do a 100% waterproof expedition one, which is more money and expands.
