If you have open feet, and your shoulders are even more open than your feet, you will go right (or smoother hard/low left). Even more so with the ball too far back. A very steep attack on the ball - usually too steep - which results in less than solid shots and some chunky divots. If/when you do hit it solid, you'll get a ton of spin though (the low burner that checks up).
Keep in mind that the shoulder line is a big indicator of where the hands/plane will be - more than any other alignment.
Sounds like you have a very 'Azinger' like motion, similar to Trevino - it can certainly be effective, but does rely on some compensations (holding off the face, clearing the hips, leg drive)
Given that motion, you would find it easier to always play a fade
