SST Pured Aerotech Steelfiber i95 stiff shafts in his irons. Aerotech makes some of the best lightweight iron shafts in the golf industry. Brant’s Ryder Cup team mate, Matt Kuchar, has been playing them the last two years. Combined with SST Puring (shaft alignment), they make irons longer, more accurate, and more consistent. Several other top touring pros, including Matt Kuchar, Tim Clark, and Ryan Moore are also playing Steelfiber shafts in their irons.
