Pros: It keeps up with the excessive torque applied on it
I actually still use the R7 Super Quad TP 9.5 with the 75 G Super Stiff shaft. My swing speed is 118 to 122. Avg. ball flight, 308 yards. I absolutely love the club and even though I've tried the R 9, R 11, R 11s, I stay with the R-7. They'll never have another like it again.
