I saw Adam Scott recently trying out the as yet unreleased prototype 915 D5 Driver which is rumoured to be at 400cc? I play the Titleis 983e driver which is a few years old now but at around 385cc.
I want to upgrade my driver but don't like large headed drivers. Is there any plan to release a 400cc driver in the near future? That would be just my cup of tea. If not, any chance of getting hold of an unused prototype as this size? Is that even possible?
