Hello, I am looking to upgrade the shaft in my 913D2. I was looking at the 2014 custom shaft catalog, and I see the Fujikura speeder 569 and 757, but the 661 does not appear to be available. The Fujikura speeder 661 is the only shaft in that line that fits my swing speed, desired launch/spin characteristics, and swingweight. Is the Fujikura motore speeder 661 available as an "off menu" shaft? How would I go about getting that shaft?
