As for wood, I heard one or two pros betting their damned lives that would be Cuetec R360.
That noted, none of them both plays with that shaft now. Both switched for carbon, and primapily for sponsorship reasons. So just another sign that low deflection is not everything for a player. Had it been such, they would have stayed loyal to their shaft with lowest deflection they ever seen. Instead, they just adopt to something else, and that's the way it should be. Just study the shaft you own now, fair and square.
