The weight is 2 grams heavier from the titanium wire that is helically embedded onto the surface of the shaft. Due to the properties of the titanium material and the TBT technology, the shaft offers a firmer feel at impact while maintaining the smooth flex that our golfers have come to love. More importantly, the excessive shaft flex at impact is reined in to help the clubhead stay square through the impact zone, resulting in less miss to the left (hooks). In terms of feel, the TBT shaft will feel soft like the original FF38, but will feel much firmer at impact (similar to a conventional 5s shaft). It is great for golfers that wish for distance and accuracy of a soft shaft, but prefer a solid firm feel at impact. The FreeFlex special-series driver shafts are our flagship products representing a decade-long research into making the impossible, possible. Using our ground-breaking FREEFLEX TECHNOLOGY, we have successfully solved the age-old issue of distance vs. accuracy, in which one no longer has to give up on distance in favor of more accuracy or vice-versa. With a much deeper understanding of the golf shaft in a dynamic action state rather than in a static state, we discovered that the three shaft variables of weight, flex, and torque can be engineered independently in any desired combination - something that wasn't thought possible. As a result, FreeFlex shafts offer the benefits of a softer shaft for faster clubhead speed without additional strain on the body, while providing the torsional strength of a firm shaft to resist twisting at impact for better accuracy with less dispersion. The result is a truly unique shaft to add more enjoyment for golfers of all skill levels and swing styles. We believe FFT represents the next step in shaft manufacturing methodology, and invite you to explore the possibilities of our cutting-edge technology.
