Both new TS fairway models feature similar technologies as the drivers including extremely thin crowns that are 27% thinner for lower and deeper CG locations thinner clubfaces with variable thickness for more ball speed distance and forgiveness on off center hits and better weight distribution for higher MOI and stability.
Like the fairway woods the Z-series hybrids are not adjustable but come in a selection of lofts including 16° 19° and 22° models. Project X HZRDUS Black 85 shafts and Golf Pride Tour Velvet 360 grips come standard.
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.
