If your bag rattles alot then you need to pay attention to your latch mechanism. My right bag has been trouble since day one and it was so loose that it wore a notch on the hing mechanism that locks onto the U-bolt. I put a pencil in the rubber cushion near the latch and halve also put weather stripping on the underside of the bag and it has helped out alot. I love the size of the bags on the X bikes but they are not designed that well.
