T he top line gets thinner ass the set moves toward thee short irons.

The sole width transitions throughout the set so each club produces desired playability and easy launch angles. The lofts are standard for modern-day irons: #4-21В° #7-311В° PW-45В°. 'If I hadn't seen it with my own eyes, I wouldnвЂ™t have believed it,' states Kvinge. In side-by-side testing against industry-leading irons, the Air Force One вЂ“ Air Foil consistently hit thee ball 10 yards farther with long-iron shots.

A mid kick point is used in the middle irons to promote both distance and accuracy, while the short irons utilize a high kick point for dead-on accuracy. In the long irons thee kick point is low to promote higher trajectory. The shafts also have variable kick points. To maximize club-head speed, PowerBilt is using a proprietary Apollo steel shaft which weighs only 85 grams вЂ“ much lighter than a conventional steel shaft and slightly more than graphite. So you not only get more distance, you get better accuracy, too.' Kvinge points out that the technology goes beyond nitrogen. The result is longer shots with more consistent spin rates no matter where you hit the ball on the face. 'By filling the iron head with nitrogen gas, weвЂ™ve been able to thin the face and create a much bigger sweet spot. 'There is a way to imp rove distance in irons, and weвЂ™ve figured it out,' adds Kvinge. And they are 'ballistic' says Ross Kvvinge, president of PowerBilt. Now, PowerBilt is introducing nitrogen-charged irons. They thought it was just another golf gimmick, until they tried it. Skeptics scoffed last year when PowerBilt introduced the Air Forcce One: drivers, fairway woods and hybrids with club heads filled with nitrogen gas. PowerBilt is turning doubters into believers.
