Is the Mitsubishi Diamana LTD. Blue 60 that is listed as a stock shaft on the 917D2 webpage the same as the Mitsubishi Rayon Diamana Ltd S+ Blue 60 that I was fitted for? Are they two different shafts or is it just how it is listed on the website? Any info would be helpful as I plan to place the order Monday morning and want to make sure I order the shaft I was fitted for.
