Mark, how does the DVS work in the SQ. I have an SQ but could never keep it in the fairway with the Pershing shaft currently installed.
I tend to be a very good driver of the ball with Callaway products and a not so good driver of the ball with Taylormade, going all the way back to the original Ti bubble shaft driver. I'm also crooked with the current burner offerings, but as straight as a skilled archer with the R7 limited, but twenty yards short of every Callaway I currently own. I've always like the SQ head and often thought of swapping out the shaft in hope of better performance.
My current gamer is a FT-5 with a NVS which I hit long and straight (most of the time). But to be honest, I currently have 22 "current" drivers sitting in an old staff bag in a spare bedroom, each of whom are yelling "pick me" every time I go play.
