I have a 915D2 with stiff Rip Alpla 60g and am looking for the right shaft for a 915F 3 wood. I have 2 questions:

1. The Rip Alpha 60g was listed for a torque of 2.9 which I bought it. But now the online specs list torque something like 3.6. Has they changed the shaft or the measurement system?

1. Is it important to match my 3 wood shaft somewhat close to the driver in weight and torque? I hit the915F with stiff Rogue 80 pretty well, but am not sure if I should look at a lighter shift with similar torque to gain some yardage.
