Looking for a bag/case/vessel for the Manfrotto 420B. Manfrotto doesn't make a specific one for it. Would like to get a bag that it fits rather snuggly into. Does anyone have a particular bag for this stand that they really like? BH suggest the Hakuba PSTC 400 Pro Series but I'm afraid that it will be too generic and just bounce around inside of it. Any info appreciated. Thanks!!
