Those foldout dump pouches are absolutely mint aren't they? fantastic forage bag or able to hold a fair amount of kit when webbed onto stuff.
tbh i've had 4m of OD webbing i've been meaning to sort out my own molle panel on my 66l and my 44l bags, the 44 should be particularly good for this as it has no middle pouch. i'm yet to find a decent sewing machine or a company that'll do the stitching for me though.
