TaylorMade Golf has introduced a new addition to its rac family of irons: the rac HT. The rac HT (which stands for Higher Trajectory) is engineered to deliver a higher level of performance at average clubhead speeds. Key to the HT's performance is its exceptionally wide sole, exceptionally thin clubface and modified tuned weight cartridge. Thanks to its low centre of gravity, the rac HT requires less effort to launch the ball into the air. An added benefit of the rac HT's wide, cambered sole is that it glides smoothly across turf, discouraging digging and promoting solid contact. Like the rac OS and rac LT models, the rac HT incorporates a Tuned Performance Cartridge inserted into the lower rim of the cavity to move weight from the sole into the club's perimeter. The rac HT's Tuned Performance Cartridge is larger than that used in the rac OS and rac LT, allowing for a displacement of 28 grams to the club's perimeter, as opposed to 21 grams for the OS. This displacement results in a higher MOI for the rac HT, for added stability and forgiveness on mis-hits. The rac HT's Tuned Performance Cartridge is also oriented differently than that used in the rac OS and rac LT to increase the low centre of gravity. The rac HT is engineered to produce a slight, distance-enhancing draw via the combined dynamics of the CG location and shaft characteristics. Plus, lightweight graphite or steel shafts help to promote added clubhead speed, which can result in more distance.
