Inserts give golfers this exact feel, therefore insert putters are considered as being softer than milled putters. With advanced technology, the variance between the two has largely diminished due to a process known as "deep milling" that makes for a very soft feel on the milled putters. Deep milling has the effect of allowing less contact ...
