things that worked for me back when I rode behind a little boat:
I liked the shorter rope and slower speed because the upward angle of the rope added to the lift factor, and the wake seemed steeper and bigger closer to the boat at a slower speed (trimmed up a bit).
I liked to load up the line as much as possible right before release because it would give me that extra whip/pop factor.
I would look up over my left shoulder, stand tall as I left the wake, give the rope a little tug once airborne, and then tuck and roll to increase my spin rate.
I would let go of the rope with my rear hand once I felt like I had enough height and rotation to get around.
I learned by trying all of this at a very slow speed, to where I wouldn't hurt myself but knew I couldn't make it. People were very patient with me trying over and over again until I was comfortable, because it was my boat
