The Mini Driver which TaylorMade offered in SLDR and AeroBurner models was a very cool product. It nicely bridged the gap between a driver and fairway wood. For a lot of players that was a perfect fit as the added loft and shorter shaft of the Mini gave them exactly what they needed.
Replacing the previous Z 565 model is the new Z 585 which is designed to produce a higher straighter ball flight than the Z 785 with more forgiveness on strikes away from the enter of the clubface.
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.
