The base S9-1 (as distinguished from the S9-1 Pro drivers - more about those on the next page) come in six Speed Tuned models: F, M, M offset, women's, women's offset and senior. What do the F and M mean? Here's how they break down in player profile:
- The F model is square-faced and tuned for a slight draw bias, a high launch and low-mid spin.
- The M model is draw biased with a high launch and mid spin.
- The M offset has a greater draw bias and higher launch with mid spin.
The S9-1 F Driver comes in lofts of 9.5 and 10.5 degrees; the S9-1 M in lofts of 10.5 and 11.5 degrees; the S9-1 M Offset in lofts of 9.5 and 10.5 degrees. Cobra/Aldila DVS-HL shafts are standard for all three.
The S9-1 senior driver and S9-1 women's driver have lofts of 11.5 degrees, while the S9-1 women's offset carries a loft of 13.5. These drivers come standard with lightweight Cobra/Graphite Design Tour AD YS shafts.
The MSRP for all six models is $375 and they become available in early February 2009.
