Reviews of various Graphite Design Tour AD shafts are being published, with different outlets evaluating different models such as the CQ, GC, UB, IZ, FI, and HD. The reviews suggest that Graphite Design Tour AD shafts are being tested and compared, although it is unclear which specific model is being considered a "game changer". A review of a Mitsubishi Diamana RB shaft is also being published, potentially as a comparison or alternative to the Graphite Design Tour AD shafts.
