I think you probably don't have them attached the same way I've seen them. The lower mounts were clipped on, and the center point in the back of the straps was tucked under the two small straps at the top of the back of the bag. The other two attachments on the quads were just tucked inside the back of the bag out of the way. That kept the top of the bag right up against the wearer's back.
Is there anyway you could post a pic so I can see this setup? If I could make it work, I'd be one very very happy golfer and my lower back would praise you.
