I haven't read the whole thread but is the contention here that a screw ball doesn't break?
I would agree with all of the following -
A screwball is a difficult pitch.
Many pitchers who throw a "screwball" get very little break on it.
It is easier to get more break on a curve ball than it is to get break on a screwball.
A good curve ball will break more than a good screwball.
I would not agree with -
A good screwball does not break at all.
