The John Letters T-Series driver has a 460cc head and has been crafted from ultra lightweight and strong Titanium. This has allowed the John Letters designers to create an ultra forgiving design, for maximum forgiveness on off centre strikes. Each T-Series driver features a DWS (Dual Weighting System). This moves the centre of gravity low and further back in the head to give a high ball flight with very little back spin for the optimum ball flight and maximum distance. Placing a large amount of the club head's weight further back, increases the MOI (Moment Of Inertia) to reduce club head twisting on off-centre strikes for more accuracy. The Titanium face used on the John Letters T-Series drivers delivers explosive power for monumental distance and a ‘Power Bar' has been designed into the crown of the club head to direct more weight directly behind the ball at impact for a solid feel and great sound. The lightweight, 65g graphite shaft, has been purpose designed for the John Letters T-Series drivers to give the maximum distance, balance and accuracy possible and a John Letters 'Softie' style grip is fitted to each of the clubs for great traction and comfort in all conditions.
