If you want to run a swaybar on the road and not on the trail, it's an option. Personally, I think thin the rear swaybar in the X is a joke to begin with and as soon as you add a set of AAL (or new "stiffer" spring pack) the swaybar does nothing.
Besides, reconnecting the Jeep is annoying enough and you don't have to crawl all the way under the rig. I would hate to have to lay under a mud covered vehicle to reconnect. Though, with the X, you could stay disconnected until you got a chance to spray it off underneath.
