Excellent - thanks for all the replies. Time to buy more Tom Bihn stuff !

Does anyone have any experience using a packing cube with the Brain Bag ? If so, which cube is the best fit ?

Many thanks.

Maverick - thanks for the reply - I keep going back and forth between the buzz, ego and imago as my next bag to compliment my brain bag.

Maybe I will have to get all three !

I have seen the very nice pictures of Leica and lenses in a Buzz bag. Does any one have any experience with using a Buzz to carry a larger DLSR like Nikon D5000 or Canon 500D with a mid sized zoom...
