+1. You need to have a vague plan or idea what the ball is supposed to do, even on a THS. You still have to take into account the basic factors of the total equation like balls specs (RG, RG. diff, is it symmetrical or does it have a considerable MB?), coverstock strength and finish, oil volume (THS can be ANYTHING, from a soupy bog to almost desert conditions), lane surface, plus the player's style.
Besides, desired reaction shape is important. When does the ball hook, when does it stop? Big hook does not mean big carry, skid/snap can create control issues, an arcing ball can tend to roll out and hit weakly, etc. It is always a compromise.
There ARE no-brainer setups, though, like a label layout on a symmetrical ball, but these will surely be sub-optimal.
There's no simple answer to this - unless you get ripped off by your ball driller
