- Model 321Li hybrid long irons are the ultimate in true hybrid long iron design due to the accompanying design of the matching GI-335 graphite or the Series 5 Steel small tip iron shafts
- TWGT research has shown that the shaft can be a visible contributor to the launch angle, but only if the shaft is designed to bend/deflect an amount much greater than is typical with a conventional iron shaft. Typical iron shafts have a larger tip diameter which can only bend/deflect 1-2" in the swing. The GI335 and Series 5 Steel .335 shaft are designed with the same butt stiffness as a conventional iron shaft, but with a small tip design to increase the launch angle and trajectory of the shot
- 321Li full hybrid long iron heads are designed in a #1, 2, 3, 4, 5 and 6-iron. Matched with any set of irons, the 321Li offers golfers a much higher trajectory from the bending of the unique small iron tip design of the GI-335 and Series 5 Steel shafts
- 321Li full hybrid long iron heads are designed with a hosel to face position that is much more like a true iron for the proper appearance and set up at address
- A cross-section view of the wall thickness of the 321Li head design shows another reason for the easy playability of this model - the rear wall of each 321Li is extremely thick to pull the CG farther back from the shaft to further assist with increasing the launch angle of the shot
- 321Li full hybrid long iron heads are finished in an attractive dark grey metallic with bright satin highlights on the sole and toe/heel
