Hi, I'm a noob to kiting as well - I cracked my waterstarting on new years day this year

I went through exactly the same process, with similar levels of confusion

I think the best thing to do is aks you instructor to let you try the different types of kite under supervision. Then bear in mind that each instructor around WA likes different kites so you can always try different instructors for different kites, if you have deep pockets, and you don't mind conflicting opinions...!
whatever kite you decide to buy I reackon the following are sensible priorities (only my opinion though!)
1.safety - latest and newest kites are much safer than those of 3 - 5 years ago. As a beginner you're gonna stuff it up a few times, so you need to be confident in the safety systems reliability and effectivness (normally not a problem with latest kites of all makes).
2. ease of relaunch - once you've stuffed up, or released your kite because you're being careful not to get into a dangerous situation, you need to be able to relaunch easily, from land
and water!
If you can relaunch easily (2) and you have confidence that using your safety (1) system isn't going to cause problems / is realiable, you'll gain confidence quickly and learn a lot faster.
3. If you can buy new the kite is in perfect condition, as your first season is going to put some serious wear and tear onto it. If you decide that the sport's not for you the kite will have some residual value after 6 months or so. It's frightening how quickly this gear depreciates in value.
If you can read through magazines and forums and manufacturers websites, you'll start to get the hang of whats, what in terms of Cs, LEIs, BOWs, Foils etc and take your time in choosing the right gear for
you.
I'm very happy with my kite, I got it on recommendation of my instructor. I'm sure other makes of kite would be just as good but I was able to try this model out in a range of winds during my lessons.
Hopefully you will be stoked with the kite you get as you'll stand up, do your first jumps, carves etc with that kite.
Hope that helps!
