Colin Montgomerie is not playing well and may employ two drivers, a-la Phil Mickelson, to get him out of the slump.

Colin says (quoted from scotsman.com), that "Phil got one up on us all by carrying two drivers in his bag as he ran away with the Bell South Classic and the Masters.Drivers can now be made with a swing bias in them, to fade and draw the ball. Phil's done very well and he won't be the only person doing it from now on. Me? I've been in touch with Yonex already with a view to doing something similar. There are certain courses, like St Andrews, where straight is good and you don't need two drivers there. But when there's a lot of doglegs, for instance at Wentworth, on the 17th I would have to hook the ball, and on the 18th I would have to hit a fade, so why not let the club do that for you and not have to put two particular different swings on it?"  

Montgomery has missed six cuts this season. Desperate times call for desperate measures.
