Featuring a blade-like clubhead with a small cavity and relatively narrow sole the Z 785 has more mass behind the sweetspot for improved versatility as well as a new Tour V.T. sole that improves turf interaction.
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.
In addition both models feature an improved version of Titleist’s Active Recoil Channel technology in the sole creating more face flex particularly on low hits yielding higher launching lower spinning longer shots.
For players who demand more workability in a driver and more specific tuning the TS3 is the choice. Both the TS2 and TS3 are available with Kuro Kage Black Dual Core 50 Tensei AV Series Blue 55 HZRDUS Smoke Black 60 and Even Flow T1100 White 65 shafts as well as other custom shaft options.
Among those I’d start by looking at models from Bettinardi Evnroll SeeMore Happy and Bloodline. Each of these companies make high-quality products at varying price points. Furthermore they can perform exceptionally well provided you find one that fits your stroke eye and feel preference.
