Johnny On Rory: "You're asking for huge trouble when you change all your clubs and your golf ball at the same time.

From a Q&A with Ron Kroichick in the SF Chronicle, touching on many topics:

"Then I would say it's one thing to change your driver or wedge, but you're asking for huge trouble when you change all your clubs and your golf ball at the same time. I did it with Wilson, and I went into an immediate slump for four or five months.

"His 9-iron and wedge have been really horrendous, and he just lost the magic with his putting. He's hit the grand slam of things you have to watch out for when you're at the top. He's a bit of a mess."
