Am using a reverse rise LX on my Sam Hillborne with a 36t in the rear for over a year with no problem. Like Jim states, on some the upper pulley might get awfully close to the 36t cog. But it hasn't been an issue for me yet. Hopefully it won't.
Am not sure the Shadow designation is for the 36t or more for not sticking out as much from the rear chainstay. Less chance of it getting dinged on a narrow trail.
