Great session went through a dozen shafts and six heads for irons, my main weakness. Those iron shafts directed us for the driver and 3 wood so the process was easier, again several heads. Data was very convincing showing separation from old clubs and respective test clubs. All club tests very helpful and directional. Amazing data and guidance. Be prepared 171 full swings (like 3 rds) every serious golfer should do this fitting analysis!
