If you are going to use the Dekker Supreme and remove the pads to strap it on there, I have another suggestion before you do it. On the flat surfaces on the top rear of the rack (above the LED lamp), you should put some of that 3M clear protectant tape...can't think what it's called, but it will keep you from scratching the chrome on there. This is one of those "don't ask me how I know" things. When I get a chance, I'll take a few closeup pics to show you what I mean. I put it on after I already saw the scratching start and the 3M tape has kept it from getting worse. I wish I had thought of this before I used the bag the first time.
Okay, I took a few photos. You may be able to see that I have some scuffing under the clear tape. If I would have put this on before using the bag, it would be perfect. You will need a piece on all 3 flat top sections...center, right, and left. Actually, it looks much worse in the photos. It's not that bad in person, but the tape would have kept it completely protected.
