A lot of golfers on the PGA Tour use custom-made clubs, but Phil Mickelson's 18° and 22° Callaway hybrids are truly unique.

When I asked him about the 18° in June prior to the start of the U.S. Open at Bethpage, he told me, "This is a special club I actually made, taking the back part of the hybrid out so that I can open it way up and get through that thick rough."

No other player on Tour has one, although a few Callaway staff players have tried one at the company's headquarters in Carlsbad, Calif.

But don't hold your breath hoping that Callaway is going to make a version of the club available anytime soon. Justin Timberlake, who is a paid member of the Callaway Golf staff, also tried a Mickelson-spec hybrid at the company's test center and loved it. After asking Callaway representatives if he could have it, he was politely told no.

Hey, if a guy who has dated Britney Spears and Cameron Diaz can't score one ...
