I started by figuring out exactly what Murray did. Was it a power slide? No. Was he on a whip? No. Technically, it was a switch hard lean. The move consists of edging away from the wake on your toes and lowering your body until it's flat against the water. As you can see, my shot was not as glamorous as Murray's, but I did experience the feeling, and I think this is pretty attainable move for any rider who's comfortable on his wakeboard. I recommend trying it yourself because it's funny when you crash, and if you don't, you'll find yourself gliding across the water like a legend.
