Thank you, Mike. I'll add one more thought.
IMHO, someone looking for better powerlifting squats and deadlifts will be better served by heavy two-handed swings than by the single handed version. This has been pretty widely discussed elsewhere, e.g., some people say that a heavy kettlebell swing can even take the place of speed deadlifts in a Westside style training template - and if not take the place of completely, at least augment them in ways difficult to do with a barbell.
