Did you hear about it?
It was on golfweek.com>>>> article
Mickelson used a Taylor Made fairway wood at the HSBC
The article quotes Mickelson:
"When I come over here, a lot of times I’m not able to hit driver and I’m right in between clubs,” Mickelson said. “And our 3-wood and driver weren’t ready, so they let me use a different club, which is why I love my relationship with Callaway. They want me to play whatever I have to play my best.”
Callaway does not seem to expose their "other" new wood line yet.
We will wait and see what it is soooooon.
