I have IRC Mythos XC tires now, and am looking forward to trying a different set for comparison and contrast if nothing else. Maybe I'll try the wider up front, narrower in back combination as well.
Thanks again for taking the time to respond.
Be aware that tires can be rather specific to areas too. What works in Colorado doesn't in New England, for example. It's usually best to ask around at your local shops or clubs to see what works for people in your area.
