Callaway is taking pre-orders on their new woods, Optiforce that offer the ability to change the loft and face angle by using the same sleeve featured in the Titleist 91X line of woods. There are two versions of the driver, 440cc, 460cc. Callaway execs claim the Optiforce is very close to the X-Hot numbers on launch monitors in terms of spin but the lighter head can produce club head speeds that are up to 4mph faster than the X-Hot.
Mid-season release of a new line seems strange for Callaway but they may be taking a page out of the TM marketing book and using the Optiforce to compete with the R1 Black. Callaway is enjoying great sales this year, especially compared to the last few years, mostly due to the X-Hot line popularity.
