In a related question regarding follow-through, I've noticed that I tend to start my follow-through just before I contact the cue ball.  That is, the tip starts dipping towards the cloth (i.e. via natural pendulum motion) just shy of contact.  Due to this, I don't feel like I'm stroking with a level cue.  In fact, I feel like my contact point between my cue and the cue ball is the top of my tip rather than the center (on center/high English shots).  When I try to correc this by forcing a level stroke at contact, my follow-through feels forced and unnatural.
Now that this is as clear as mud, any advice or observations?
