No thoughts come to mind. Actually, I dunno about the leg straps, but we usually use a type lll PFD, but you may want to read up on the type l PFD's on the market. They are for different conditions and scenarios.
I don't have any blazing PFD photos, but I do have one of where a SAM hit an Airbus cargo plane over Baghdad.
