Using a wrench, golfers can remove the head of the R9 and R9 TP and then re-attach it in one of eight different positions. Each of the head positions offers a different effective loft, lie angle and face angleranging from 2° open to 2° closed. In combination with the positioning of three adjustable weight plugs (one 16-gram and two 1-gram), TaylorMade says golfers can dramatically adjust their ball flight.
