Picking my usual nit about this:I believe that CF transfers more energy to the cue ball, so you will get more spin/draw/follow from the same stroke with CF than you will with wood.
More energy means more RPMs, but also more speed - and since the spin-to-speed ratio is what's important for most spin effects, you don't really get "more spin" except when the CB is significantly slowed/stopped by the OB (like with follow/draw).
And you can produce the same effect with any cue by simply hitting a little harder.
