Currently sporting some roll-x tires on my 04 stump fsr comp. Almost time for new tires and I was looking at the resolution tires that come on the current stumpies. Any good? I ride in new england (think tight twisty singletrack, plenty of rock gardens and roots). I like the roll-x's but wouldn't mind trying somethinge else. Can go tubeless as well for I have mavic crosslands currently.
