Tom, I really like the rack. However; I do have another suggestion based upon my experience with a bungie net on top of my tank bag on my CBR 600. I'm wondering, in rough terrain, if four bungie hooks is enough. On my CBR, when I ride hard in the twisties, aggressively accelerating, decelerating, and leaning from side to side abruptly, the four point attachment for my bungie net-to-tank bag was not enough to keep things under the bungie net under the net and the G forces allowed whatever I had under the net move forward, backward, or to the side between, and sometimes out from under the bungie net hooks. I went to a shoe shop and had them add four more hooks to my tank bag, one between each corner. It works great and keeps everything under the bungie net in place.
How about one more hook between each corner?
