How tall are you? The x gives more suspension travel & in turn gains height. I have a uly xt as well and the thought of extra height and size/weight are not appealing to me . I'm 5'9" and have ridden dirt bikes all my life untill my xt,I would opt for lighter 600cc bikes for any real "off road" adventures. A uly can do the job,but tends to be heavy for true off road situations. Fire roads would be no problem,but logs,big rocks,big holes and washes my be tricky.
