Project X LZ Shaft Review

The introduction of the LZ, or Loading Zone Technology, helps bring the precision and advantages of Project X to a broader player profile. The Project X LZ shaft is built for players looking to get a slightly higher ball flight and more responsive feel from their iron shaft.

Project X LZ Shaft Detailed Review

Design and Technology

Project X has been incredibly successful in making iron shafts for the game’s best players and very strong swingers. To their own admission, however, the standard Project X iron and wedge shaft does not fit the need of most amateur golfers. Enter Project X LZ. The Project X LZ maintains all the playing benefits of the standard shaft but gives players easier launch and an improved feel, especially at slower swing speeds. Players that have always loved the performance of Project X but felt they had to work too hard to play them consistently have a great new option in the Project X LZ. Loading Zone Technology redistributes the weight of the shaft for ultimate stability and a signature smooth feel.

I play Project X shafts in my irons and love the performance benefits of Project X’s design. The LZ shaft is perfect for players that want similar performance but do not have tour-level swing speeds. Overall, I felt immediately comfortable with the LZ shafts and loved the feeling I was receiving with my 7 iron. Through age or diminishing swing speeds, I will have no problem transitioning into this incredible engineering accomplishment.

LZ combines the benefits of premium materials into a brand new design that gave Project X the ability to couple responsiveness and feel into an ultra-stable iron shaft. Players that are looking for the performance advantages of Project X with a smooth feel will love the Project X LZ. LZ also makes a great option for players looking to transition their wedge shafts into something slightly softer, especially if they are playing Project X standard shafts in their irons.
