I dont understand the idea of a lighter shaft and flighted.
Lighter shaft for increased SS and then flighted shaft for a lower flight with shorter irons and higher flight for longer irons.
Maintain the characteristics of the flighted shaft while the lighter shaft gives increased SS along with less tiring (common reason that was cited in the Tour 90's testing thread).
At least this is how I think of it and why it intrigues me.
