A consistent little draw is a great thing. Knowing you wont double cross yourself is a great great advantage. Id say go with the draw especially if you really have to overdo things to hit a big draw. Thats amazing.

But to answer your question there is but one answer ....... Divergence. Ball flight laws work.

That said , when I see guys adjust the plane line and face angle for a curve ball I always see a little "helping hand" or Release manipulation in there too. Hold off for a fade etc. Science and art combined. In the end we're artists, ideally Id say. The #3pp is our brush the Visual Equivalent is our canvas. You can paint the curved arc or a straighter angle intuitively by feel but it helps to be set up appropriately. Really helps. Like an artist drawing in perspective needing his horizon line, vanishing points etc. Art yes but within the frame work of proper geometry. Underneath the final work there are pencil lines which are no longer visible.
