Very good. Honestly, 540s are easier than 360 once you get them. Make sure to keep up your 540.
Eubanks, try standing up taller at the wake. As I move into bigger spins I have a tendency to lean too hard at the wake. Leaning too far forward on the approach will equal leaning to far back on the 540 landing.
Rather than leaning the top half of your body over your toes to generate leverage, try keeping your chest up and dropping to your knees. All the leverage with no break at the waist.
