Pick one?
It would be benificial to pick the ALIGNMENTS that work for you.
In other words, if you play better OPENING the face to the plane, fly at it. If you don't—keep that sucker lookin' at the ball.
If you play better FELLING LIKE you use RIGHT ARM or LEFT ARM or both, use the one that works.
At the end of the day, the only difference between Swinging and Hitting is alignments and feels.
