The Tour V.T. sole improves turf interaction as well. Both new models come standard with Nippon Modus steel shafts with a Miyazaki Kaula graphite shaft also available.
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.
