Summary: I currently play with a Srixon W-506 which is at 450cc. I just got a Z-RW 460cc to see if the 10cc of additional forgiveness will help. The driver is just as long, but the first thing I noticed right away was the high pitch "ping" sound at impact. This sound reminded me of a slowpitch softball bat.
Summary: This driver is the best I have ever used. I can blast drives of between 300 and 330yds with my swing speed of 110mph with this driver. I have the 8.5 degree, with an aftermarket, Pro launch stiff shaft. I like the appearance of this driver, and the great feel of it.
Summary: This is the longest most forgiving Driver on the market today. I have 2 same loft different shafts for different playing conditions. The whole face is a sweet spot, the only driver more forgiving is the Alpha RX 460 but it is not as long as this one.
Summary: I stumbled across this club second-hand, after looking for the Grafalloy Epic shaft. I have been using the Mizuno MP600 of late which was the best for me after being custom & swing assessed. The only problem with the Miz is its small 'sweet spot'. Tried out the Srixon and have been blown away ..
Excerpt: Bought the Srixon Z-RW after have a terrible year off the tee with my Wilson Driver. I had previously had a Srixon W-403 (conforming) driver which I loved, stupidly I wanted a new driver and therefore gave it to my Dad.
