Many GolfWRXers speculated that Mickelson was playing a 3 wood of some sort with a slot on the bottom at the World Golf Championships-HSBC Champions in China. While the club appeared to be a black-painted TaylorMade RBZ fairway wood, the photos were inconclusive, leading to theories that the 3 wood was actually using a soon-to-be-released Callaway product.

We’ve learned that Mickelson is indeed using an RBZ 3 wood in China, albeit a heavily modified one. It is bent 11.5 degree and includes a lighter-than-normal shaft for Mickelson as well as a lot of lead tape to lower the center of gravity.

Not Mickelson’s, but an example of a black-painted RBZ

How do we know? Frequent GolfWRX poster and Callaway Senior Vice President of Marketing Harry Arnett confirmed it in the forums. Read his post in its entirety below, in which Arnett rewards a GolfWRX member for discerning from photos that Mickelson was using an RBZ 3 wood with a prize, and provides other members with a dozen HexBlackTour golf balls.

“First of all, these guesses here were awesome. And I am going to make our R&D and product guys read this thread because there were some killer ideas/concepts you guys threw out. Should have known that the dark knights of club ho-edness could come up with some cool stuff.

Here’s the answer, and I think it will surprise many of you. But like I said when we jumped into this and as part of our mission to be a “different” company, a new company, we are going to do things differently and be more straight shooting and transparent.

About two weeks ago, Phil said that the HSBC at Mission Hills isn’t a course where he can hit driver at all. He doubted he would hit driver on any of the holes. He wanted to play a high COR fairway wood there because he wanted a club that went farther than his current 3 wood but not as far as his driver. He knows we have one coming and he asked to play one of our prototypes. Unfortunately we are not ready to launch this product yet and didn’t have the right lofts in left-handed for him.  Our primary interest is supporting our players at all times so we told him to play whatever he wanted until he thinks we have the best possible product for him which we believe we will have imminently. This is pretty much standard operating procedure for us. Not well known to many is that Phil has one of the most flexible equipment contracts of any top player and has played other equipment from time to time during his relationship with us, and is well within his right to do so.

That, gentlemen, in Phil’s hands, is a modified RBZ 13 degree, bent to 11.5, “driving 3-wood.” Phil painted her up matte black because he thought that looked cool, put in a lighter shaft than normal so he could actually launch it in the air, and put a crap load of lead tape on the bottom of it to move the CG location so it could actually get up in the air. Result? He has a mini driver that’s good for 290 [yards] off the tee, right between his current 280 3 wood gamer and his 305 driver. Ladies and gentlemen, I present to you, Phil Mickelson, the Crowned Prince of this Forum and club junkies everywhere.
