In order to make the necessary jump in distance the new Z F85 fairway woods are built with the same speed-enhancing Cup Face design as the new drivers as well as a lightweight carbon crown for higher MOI and enhanced forgiveness.
Though Srixon has long been known for impressive forged irons the woods were always high-quality products that were often overlooked. With the new iteration including most notably the Z 785 driver things are about to change in a big way as new technologies and materials have brought ball speeds (and distance) up to the level of the longer drivers on the market.
However I’d say it’s unlikely that a new iteration of the Mini is coming any time soon. Modern fairway wood designs like TaylorMade’s M3 and M4 for example are so good and so long that former Mini players can simply find the right fit and most likely get the same or even better performance.
