I use this BAM 8004XLC 16" Arch Top Case for travelling, by foot and public transport between gigs of an evening. It makes carrying my Gibson L4 a real joy. I often don't even use the shoulder straps as the guitar is light in this BAM case and, easy to manoeuvre.
I could not find anything that I did not like about this case and on the plus side, it fits all my 16" Arch Top guitars very well (and I am very fussy about the care of my instruments even though I play the hell out of them). Up until now I have not found a need to use the extra foam padding which comes with the case.
This case has been knocked over once so far, while it was stood on it's heel with me at a bus stop. I didn't even want to look at where it made contact to the wall before hitting the ground. But, it only dented slightly and didn't actually scratch and, most importantly, the guitar was undamaged. The dent on the case only went as deep as the 1cm case-structure and did not penetrate to the inside of the case.
My overall view of this guitar case is that it is an excellent case for the working musician. In time I will purchase one for my classical/nylon strung guitars as I find the case a joy to use.
