Spot on all of the above. Had a 16 several years ago. Always out solo. The 16 is a handful in moderate to heavy air if you're alone. The wave I've had for about 2 weeks. Out last week in 10-20 with 25mph gusts. The wave screams and is exponentially easier to handle in big air if solo. I was out today in around 5 to 10's working out some bugs and it's a drag in anything under 15 unless you want to putt along. If you want a thrill, the wave is the way to go if you sail in heavy air alone.
