If you had to put this one in the bag when it counts, what would you do to get it to the most optimal playability? (Does that make sense?)The sweet spot is not any smaller...Its what happens when one misses that sweet spot that changes things. Look at it like an iron.
Balance point of an iron is virtually the same no matter the size of the iron. However take a muscle back iron, with weight directly behind the impact balance point, and miss a bit. Then do the same with a larger club head with perimeter weighting. Many would refer to it as a "smaller sweet spot", which in a technical sense is not correct.
However the lateral forgiveness is not as large. While many club companies have worked on expanding the optimal hitting zone, going ultra low spin, with weight direct behind the impact spot rather than further back, can impact forgiveness in a number of ways.
High launching shaft? Higher spin shaft? Close eyes and pray?
