I think the Holeshot rack looks nice, but also looks like it wouldn't carry much. I opted for a bigger rack (Ventura), which also mounts in more than the grab rail location. Racks that mount only to the grab rail location are known to break subframe structure if the Suzuki recommended maximum load is violated very often (I forget if it's 10 or 15 lbs.). Since I have a Corbin seat, I use their backrest for passenger security. It doesn't interfere with the Ventura Pack Rack either... but might not work with something like a Givi trunk.
FWIW - the Ventura racks come off in ~30 seconds if you leave the mount brackets on (loosen two thumbscrews and lift it off), and the same 3 minutes to remove as the Holeshot if you want everything off since it also has just four mounting points (where the four bungee spools are).
