The Dart 16 is just as bulletproof as the wave and its got more horsepower.
I'd vote for the Dart 16.
I don't know the Wave, but our juniors (early teens) turned their noses up at the Twixxy in favour of the Dart 16. They could handle it too, up to the top of a force 3.(not reefed.
The new Topper is also designed by Yves Loday and looks cool <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />. I have not sailed one.
