Perfect Ball Launch is what every golfer hopes for when using a golf putter. But that is simply not possible when using a defectively designed golf putter that lacks Polar Symmetry. One golf putter enables the perfect ball launch that every golfer wants on every putt.
Hold your putter loosely with one hand as shown, and then with a finger of your other hand tap the place where you usually strike the golf ball. If the putter head twists when tapped, it does not have the polar symmetry required for sweet impact and is not worthy of being in your golf bag. .
Wobble is the annoying rotation of the putter head with reference to the power vector (shaft) and it is caused by an out-of balance putter. Wiggle is the annoying waver in the putting stroke caused by wobble. Both are devastating for putting performance. One golf putter suffers none of this.
Dreaded Impact Twist comes as a result of Miss-Vectored Shafting. Perfect shaft vectoring is a characteristic of Polar Symmetry. Without such vectoring, the ball's mass will always cause the head to twist upon impact. That twisting in turn causes the ball to be launched off intended line. One golf putter suffers none of this.
It is a principle of physics that enables Sweet Impact and it is what an any impacting tool needs. Tennis racquets have it. Baseball bats have it. Pool Cues have it. And Golf Putters should have it too. But amazingly most golf putters including Ping Style Blades and Odyssey Style Mallets lack it. One golf putter has it and that makes it better than all the other golf putters that lack it.
Hold your putter shaft between the palms of your hands as shown, and then move your palms back and forth to rotate the shaft to and fro (as you would do when testing a pool cue for playing suitability). If there is any wobble, then your putter lacks the required polar symmetry for sweet impact, and it is not worthy to be in your golf bag.
Sweet Symmetry is the Big Idea in Golf Putters and the difference between Good and Bad Golf Putters -- the Good have it and the Bad lack it.
