Michelin doesn't make a tire for the XCT. E3, Avon Cobra, and (gasp) Metzlers 888. These are the tires in radial form that carry the equivalent load rating of the XCT.
The Stones that Broggy mentioned are fine tires and will make it feel more sporty, but be aware you lose about 160 pounds of rear tire load rating. Bridgestone has an envigor or some sort of tire out as well now. Not sure about those other than they are an 827 pound load rate as well.
Sorry to say MC tires leave a lot to be desired in many ways. If you don't go much over 400 ish pounds on a load, the 704-709 are really hard to beat IMHO.
