If you like the feel of trial tires and are an "all-in" type of rider, then go for the Michelin X-Lights. These tires are sweet, and the improved competition casings increase stability due to their stiffer sidewalls. They're softer across the crown, and the contact area is increased. They are also are a pound lighter than their predecessor for improved suspension response and maneuverability. You're sure to feel secure in the corners and fast in the woods as you overcome rocks, roots, and loose dirt. Recommended pressures for trials use 6 psi front, 5 psi rear, and they are not legal for highway use.
