STT winds up the flywheel. The BS looks a little old fashioned with the hands leaving the clubhead behind. Nice transition with the previously noted lag. Although the shaft can't be seen, the hand orientation before impact indicate that the shaft is horizontal in the frame before impact. Good passive bent right arm through impact. The next frame after the ball disappears, notice the small square area of light which shows the left arm separating from the body. This could indicate some independent left arm action in an effort to keep the hands above the clubhead well past impact. Good rotation all the way to the finish. This is an excellent, max participation, 3-barrel Swing. I'd like to see the DTL perspective, and also the "still head" version for comparison.
Great job tongzilla and Brian in building a solid pattern!
