True Temper Dynamic Gold golf shaft
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.
The shaft of choice on the PGA Tour, the old reliable Dynamic Gold (the first Dynamic shaft appeared in 1942) outnumbers Project X by a 3-1 ratio on Tour. Tiger Woods uses the Dynamic Gold X-100.
Each flex has multiple sub-flexes, so fitting with these shafts is a very personal choice. X-100 is one of those sub-categories and is popular on Tour, although some players go slightly softer with an S-400.
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
