I'm a very happy XTX owner but if the majority of your riding is ditches I would keep on the RTX SE path but replace the track with either a 1.5" or 1.75" lug. That way you still have an excellent ditch-banger while also having a sled with enough paddle to handle some decent x-country as well when up in WI or the Yooper
That's what I would do if I were in your position anyway.
