Tour Edge Exotics Trilogy Rail Fairway Woods
From Golf Magazine (January, 2010)
The three-rail sole features two outer rails and a diamond-shaped inner rail to lift the ball out of nasty lies. The inner rail, on the center rear of the sole, acts like a rudder to deflect the turf and square the face at impactif the face is open, the rail steers it into a more closed position, and vice versa. The outer rails distribute mass to the club's perimeter to improve stability on off-center hits.
