I'd rate the danger of roller skiing over cross country at a much higher level - falling on tarmac does a lot more damage than falling on snow. I'd also probably rate the fitness as higher for roller than crosscountry as I reckon its a  lot easier to take it easy and plod along on snow than on rollers. The thrill rating is very dependant on where you are skiing - eg roller skiing down the hill road at cairngorm whould definitely be a 'thrill'
