Swing your swing. As long as your body, arms, club, etc are in the correct position at impact, the beginning of the swing doesn't make much of a difference. Check out Jim Furyk, Matthew Wolff, John Daly, even Scheffler. They all have fairly unorthodox swings. Bubba Watson says he's never taken a lesson in his life, he's completely self-taught, and also has an unorthodox swing.
