Serge,
If you got fit for it, then it's designed for your swing. It should be just right for you.
my shaft feels just right to me from a stiffness perspective.
Based on a fitting session at 7D, they designed my shaft to be tip stiff and low torque because that fits my swing the best.
I get very tight dispersion when I actually hit on the middle of face. Honestly, because of the 46.75" length, I am struggling a bit with consistency. On the other hand, I am consistenly getting 110 mph SS or higher without too much effort which translates to monster distances but again, only when I hit the middle of face.
Thinking about shortening it down to 46" and also switching the head to a slightly lighter head.
that should bring down the swing weight from the crazy high D9 to a more managable D4 or D5:)
