Interesting that Tim Herron is playing combo of Ping Anser and S55. Anser are forged, while the S55 are cast. That's the first I've heard of any pros playing anser irons.
That is weird. The reverse combo. Also saw the newer Ping Ansers in another bag. I have a set of those Ping Ansers that are in Herron's bag, but I swapped them out for some Cleveland 588 CBs.
