Technically ANY adjustment made to a club's length affects it's stiffness, but it really depends on where you take the length out. if you take it at the tip, it will make dramatic differences in stiffness, while taking from the butt-end iis dramatically less-so. it also depends on the relative stiffness of the shaft in its original state, lesser shafts will firm up quickly while already stiff shafts will take more adjustment to realize a change in stiffness. rule of thumb lets you take an inch or so off the butt-end without adverse affect on the original state of the shaft, while an inch and a half will not make a huge difference, more than that starts to depend on the shaft itself.
