Agreed. FHE is appropriate on certain types of shots (e.g., long, slow shots), BHE is appropriate on others (e.g., short or fast shots), and appropriate combinations of FHE and BHE are required on all shots in between. For much more information on this topic, see:
back-hand (BHE) and front-hand english (FHE)
The alternative is to aim without any pivot whatsoever, aligning the cue in the necessary direction to compensate for squirt, swerve, and throw, based on years of practice and successful experience. To do this, one must have a solid understanding and/or intuition of
important squirt, swerve, and throw effects.
