The spin kit on the Wave is very easy to use. I uses a single line hoist and douse set up. The sail is sized well for the boat and certainly adds some 'go' for off the wind sailing but not so much that you need to be a rockstar to handle it. There is some technique required to trim and gybe the kite properly but it is easily learned. Fortunately, the sail isn't so big that you'll go swimming the hard way if you mess up
.
I've installed a few of them and none of the owners had any asymmetric spinnaker experience but they all still like them.
Feel free to contact me by pm or phone.
