Seems that any topiv on BHE or bridge lengths tend to go on and on 
I can normally visualise the shot before a shoot, but you have to visualise the correct speed and feel of the shot. When using english this is very important as bridge length and aim are important. Do you consider swirve into your aiming, or shoot so deflection (squirt) is more powrful, or cancel both out? Also consider the effect spin has on the object ball angle out of the shot. More so on outside english, but you still need to consider this with IE shots.
