Phil and Skill?

Is anyone else intrigued by the notion that Phil Mickelson is using two drivers, one to shape the ball right to left (the "gamer"), and another for the opposite shot shape?

Golf World's E. Michael Johnson has the details in this story.

In the "skill" debate, I wonder if this will come up as an example where equipment is supplementing skill? 

More power to Mickelson for doing what he has to do to win within the rules, but I guess this brings me back to Max Behr's quote about the role of equipment:

I do not think we will go far wrong if we define a true sportsman as one who endeavors to adjust his implements down to a point where they will just sustain his skill, in order that upon skill, and skill alone, must depend the decision of the contest.

A strong case could be made that good players used to use drivers with slightly open or closed faces to create a certain ball flight or to offset a swing flaw.

And I suppose you could say there is skill in determining that you get different reactions from different clubs. But it seems that the real skill in this case was in the club fitting?

It was this Telegraph story quoting Colin Montgomerie that left me wondering:
Montgomerie then considered how useful the two clubs would be at, say, the 17th and 18th at Wentworth and, again, at the last two holes at the Belfry. "The best thing about the idea," he continued, "is the way you can do away with the need to come up with two different swings."
