While at Stoke Park for the launch of the new Titleist 913D2 and D3 drivers, I caught up with the brand's US-based general manager of golf clubs, Steve Pelisek.
"Did I mention that Rory won using our new driver?" he jokes as he recalls how McIlroy first got his hands on the 913 d3
model a few weeks before his PGA Championship triumph at Kiawah Island and was so impressed he immediately put it in his bag.
Pelisek told me about the main benefits of the new drivers, as well as explaining some of the key advantages.
The launch angles are similar, we didn't want to play with that. The 913D2 is a lower spinning driver than it was, cheap golf clubs
which we think is good. We also dialled up the sound; we wanted to give a little more 'crackier' sound to it.
The 913 d2 driver
is going to be a little more forgiving driver. The D3 isn't unforgiving but it's more workable than the D2 - that's why Rory has the D3 in his bag. He liked the shape of the D2 but with that dynamic closure in the face - and slight draw bias - it didn't allow him to go after it with his drives. He felt he might turn it over too much.
The USGA says you are limited by how fast you can make a driver. But within that you're not limited by how big that area can be by shape, cheap ap2 712 irons
sound or trajectory left to right. So what we're basically trying to do is make that sweet spot bigger and bigger and use adjustability to allow everyone to dial in exactly what they want.
It's all to do with the thickness of the wall of the clubhead, how it resonates. You can do it retrospectively by putting a little more glue in the head but our designers have integrated the sounds simultaneously.
