According to Brian Schielke marketing director at Srixon Golf the newest line of Z Series woods don’t simply represent an evolutionary improvement over the company’s past models but rather a “revolutionary” one and for good reason.
Putters with more forgiveness and stability like larger mallets typically provide superior distance control because they maintain consistent ball speed and roll even on mis-hits. Unless you’re exceptionally accurate with your contact point (repeatable impact in the center of the putterface) don’t fall overly in love with the more traditional head shapes.
The newest version also features a forged construction similar to the Z 585 and Z 785 irons but is built with a hollow club head and high-strength face insert that allows the club to behave more like a wood. What this means is higher launch higher flight and more distance for a wide variety of players.
