Steel iron shafts have dominated the golf marketplace for 75 years. The reason: Consistency and stability. The process for manufacturing steel shafts is easily repeatable, and the performance from one shaft to another is highly predictable.
What is the difference between two True Temper shafts, Dynamic Gold and Project X? Both are heavy (in the 125-gram range), and they produce similar shot patterns. However, the feel is distinctly different.
During the swing, Project X feels stiffer in the grip area. Rory McIlroy uses Project X. With the Dynamic Gold used by Tiger Woods, there is slightly more clubhead feel. New Project X shafts such as PXi and PX 95 Flighted have a more responsive feel.
Steel shafts from True Temper are available down to the 75-gram range, although individual golfers must decide how light is too light. On the PGA Tour, where swing speeds are among the fastest in the world, more than 95 percent of players use steel iron shafts. Traditionally, skilled players have favored heavier weights – in the 120- to 130-gram range – but interest in lighter weight steel is increasing on Tour and among amateur golfers.
