913 d3

Is the 913 d3 driver supposed to give a lower ball flight/lower spin?

Depends on the shaft you choose. diamana white board is a low launch/spin shaft.

I just recently purchased the 913 D3 with a Bassara 50 in Regular Flex. It produces a medium to high launch. The miz MP630 I was using lauched a little higher than the 913D3; however 20-30 yards shorter. I am just amazed what technology can do.
