Remember the Mini came in 12° 14° and 16° models and had a 43.5″ shaft. If you want something like that a custom-fitted M4 fairway might be about right except it will probably offer even more ballspeed and forgiveness.
Matching putter type to stroke shape isn’t a great fitting strategy. In fact research indicates that how you “release” the putter is much more critical. Bottom line: If the putterface is square to the target line at impact it doesn’t matter what it does during the rest of the stroke. Selecting the correct hosel can make all the difference here.
Like the Tour the Forged also features a “stability frame” design with a stronger toe area and topline for increased stability on off-center hits and a new more durable Pearl Brush finish.
Like the TS2 the TS3 features the same thin titanium crown for lower and deeper CG location thinner and faster clubface for more distance and improved aerodynamic shape for more swing speed.
None of the above matters if you can’t aim your putter correctly Experiment with offset and straight-in hosels — you’ll definitely aim one type better than the other. Then check the alignment marks. Do you prefer lines that run parallel to the target? How many lines? These are important questions that can best be answered through a proper fitting.
