Kelly was kind enough to extend his black friday sale and as a result I have a Neuro X tour Boom driver head en route. The plan is to get it nice and heavy, play it at 44" and compare it to my tsi4. Winter is upon us which means less golf and more tinkering, at least out here on the west coast. So far have been really lucky with the weather with minimal rain and a couple of frost delays that have delayed tee times.
Thanks again Kelly for enabling and I'll post a review once I have a couple of rounds under my belt with it.
