I am considering changing to low launch / low spin graphite shafts in my irons and driving iron after playing Project X 7.0 and KBS C-Taper X shafts for several years, I am very interested in the UST Attas Tour 110 X shafts and I would like to hear any thoughts on how they perform and how they would compare to the Project X or C-Taper in terms of launch, spin, distance etc.
