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.
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.
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.
