Purely as research, daughter and I have just returned from a trip to HoF to look at DR....
We located one in the required Black forest, the one they had was grainier than my BF bays or the BF bays they had.
Having convinced the SA (male) we weren't bonkers, we removed all the stuffing...at which point, it turned into a black forest puddle.
The PML pocket is a flat pocket, so would take papers, but not anything of any width such as a purse or telephone without it being visible within the pocket...IYKWIM.....i don't think you would develop a crease from using it and as the SA helpfully pointed out, if you don't use it, you won't get a crease line...(no s%#*t!?)
The zip top opens the bag WIDE, and there is a fair amount of space in there, though not as much as bays....
All in all, if you like your bags with pointless pockets and lots of slump.....go get it now. If you prefer a bag with structure and useful pockets....buy a bays!
