Came here to post this.
Ping, TaylorMade, Titleist, Callaway and to a somewhat lesser degree Cobra seem to get all the attention when it comes to drivers and FW metals. Companies like Mizuno and Srixon fly under the radar being overshadowed by the above.
The good news is that brands like Mizuno and Srixon can represent a really good deal, especially in the used market or as new models come out. I got a STZ-220 driver head for a steal as a result.
