Take lessons, get the Progressions beginner video, and make friends with the locals you will be kiting with. You will learn a lot from them including
what equipment is right for the area.
Apex is NOT a water kite since it has open cells (when I had one it did). LEI will definitely shorten your learning curve. Trust me I started with a
FS Pulse and spent lots of time untangling a soggy mess. Great kite but when you are starting the kite will be in the water plenty of time. North
Rebel is a great, easy to relaunch, safe learning kite. The local schools use them and I have flown my 2011 10M for years.
Get a wide twintip to start. It will help you plane earlier and then you can use it as your light wind board. Also pick one that has visible
graphics. You will spend a lot of time body dragging back to your board. Don't get a board leash.
