Looks great - but note that all the materials specified are the same as the outgoing model, so will be interested to hear what advancements have been made to this new driver - apart from the face stamping.
The 4 and 5 star upgrades are outlandishly expensive - around 3 grand. Very interested to hear how the testing went with this 4-star model. Didn't see any mention of how it performed...or have you not tested it much at this time?
