1) 趾部和根部平衡的推杆，原文：HEEL AND TOE WEIGHTED PUTTERS – Putters with mass located on the heel and toe are more stable than other geometries. This increases greatly the MOI of putters and improves the performance of putts when hit off center. (example- the original Anser putter)

        2）空心的金属木杆，原文：OPEN CORE METAL WOODS - Before the first stainless steel driver all woods were solid core. If the core is open the club will have a much higher MOI and be much more forgiving to hit. Bigger metal woods for over all footprint and size will also have higher MOI’s and higher performance. This is only possible if the core is open without material and mass. Solid core woods and irons do not have a chance to compete against the performance of open core clubs. (example all metal woods)

         3）钛合金金属木杆，原文：TITANIUM METAL WOOD DRIVERS - Titanium is the ideal material for metal woods. It is very strong compared to its weight and allows very large high MOI drivers. There is nothing even close for drivers. (Example all titanium metal woods.)

         4）1号开球木杆从打击面到背后距离与从根部到趾部距离的比例变化，原文：SUPER BREADTH DRIVERS - Before 2005 all drivers had a ratio of .83. This is breadth front to back (B) divided by the Face Length (F) or B/F. When this ratio is near 1.0 the center of mass and MOI relationships make the club significantly better and easier to play. The Nike SQ driver was the first driver to move this ratio from .83 to a ratio near 1.0. Since the introduction of SQ every other manufacture has improved their driver performance by making drivers near 1.0. (examples- almost every driver made today)

          5）打击面面角调整，球杆快速更换技术，原文：ADJUSTABLE FACE/SHAFT METALWOODS - Woods that have off center bore adjustments (Like STR8-fit) provide multiple adjustments for loft, lie and face angles. When the shaft bore line is off axis it allows the face relationship vs. the shaft to change. This change allows multiple combinations of loft/lie and face angle. Never before has a player been able to buy one metal wood and get multiple club type performance. It is like buying 1 club and getting 8 clubs. (example STR-8 fit metal woods)

          6）球低回旋滚动的推杆，原文:LOW SKID ROLL PUTTERS – Putter faces that reduce the amount of back spin will turn over putts much faster. Reducing the back spin creates a faster truer roll to the cup. Normal face putters have high lofts and will back spin the ball as it comes off the face. The ball will bounce and skid out of control before it starts to stabilize and roll forward. Putter faces that send the ball off with zero or greatly reduced backspin improve putting performance significantly.

          7) 木杆和铁杆低而且后的重心设计，原文：DRIVERS & IRONS WITH CENTERS OF GRAVITIES FAR FROM THE FACE AND LOW - irons and woods that have centers of mass/gravities that are as far as possible from the face will launch the ball higher. Most golfers benefit greatly from higher ball flights. Centers of gravity that are low in the head do the same thing. This combo makes for the optimum club for most people. Wide soles and low profile face geometries are ways to achieve these objectives. (example-Mach Speed irons)

          8）高性能的铁杆打击面线沟，原文：HIGH PERFORMANCE GROOVES - The first U grooves removed grass and water from between the ball and face and helped greatly retain spin on high lofted iron shots. It was a big deal in the 70’s. Recently the ruling bodies have given us a new rule that moved performance back in time by their requirement for new grooves. Even with this new rule however there are some ways to make the spin better than was possible before U grooves. By close spacing and special edges grooves like the Nike X3X grooves it is possible to retain much greater spin on shots that are wet.

         9）有背穴的铁杆，原文：HEEL AND TOE AND CAVITIY BACK IRONS - This type of iron has a much higher MOI and is more forgiving than previous iron designs for off center hits. Before these types of irons all clubs were blade backs. (example all cavity back irons)

         10）轻量杆身， 原文：LIGHT WEIGHT SHAFTS - Steel first then graphite shafts made clubs overall lighter. The lighter weights allowed golfers to swing faster and hit it longer. Duh! The benefits should be obvious.
