About 8 years ago I was driver fitted at Club Champion in Chicago. The fitter fitted me for a Titleist 910 D2, with the black (12g?) weight.
He then proceeded to tell me that the stock Diamana shafts that say " Made for Titleist" are inferior to an aftermarket Diamana shaft from the factory. I ended up buying the "upgraded" iLima 60 aftermarket shaft on his suggestion.
First, is this true about the "Made for Titleist" stock shafts? And 2nd, Does Titleist Thursday fittings only use stock Made for Titleist shafts?
