Why not just build precision in the player to handle the longer shaft?
I liked the article and Wishon's company, but...Seriously, short for some. Long for others. There is no one size fits all.
I went to this old golf joint the other dude. . . old skool . . . and the old fart that ran the place had this piece of card board that he had put a matrix on . . . Loft Lies and Lengths from 3 different eras to current . . .

You should play the longest club you can CONTROL . . . I asked a question out here a long time ago about whether you'd rather have center face contact or more speed . . . HANDS DOWN HITTIN' IT FLUSH WON.
I think Eldrick was playing a 43 inch driver the year where he put everybody to shame . . . I bet most people play a driver that is too long for them and probably don't have enough loft.
