What does Rory McIlroy think about the current golf club controversy?

Question

McIlroy thinks the new regulations on the shape of grooves in the heads of golf clubs should be reconsidered. Rules have been introduced to stop tour pros from putting excessive spin on the ball, but players have attempted to circumvent the rules by playing old, exempt clubs. The Ulsterman said that instead of messing with the clubs, changes could be made to golf courses to make the game tougher.
