Just wondering about a few accessories. Wanted to get a box or bag for the back rack, is the hinged box in the catalog worth it or is the bag better. Also the gun scabbard, is the deluxe one a lot better or not? I am used to the fork gun grips on the front rack but am thinking about the gun scabbard. Just wondering if anyone could give me some insight into what has worked well for them. Just got my 06 700 and now need to accessorize. Thanks for any help.
