Second hand kite to start with as you will probably crash it a fair bit.
Hi Tyler,
6 years ago I've spent a few winter months kiting as a newbie in the central coast NSW and was mostly using my 16m kite @85kg, sometimes my 10m. From memory wind was pretty bad and I was lucky to get 1-2 sessions a week with a fully flexible schedule...
At your weight you probably need at least a 12m kite and as you said a big board would help a lot. Further down the track you may find that a 150cm board is quite big and you will want to change it, so getting a second hand board is a wise decision. With a powerful 12m kite and 150cm board you will still need a bare minimum of 15-18 knots to get going easily and probably start to get overpowered a bit below 25 knots.
The second hand kite market is very tricky for newbies, as you often don't know exactly what you're looking for and you can be tempted to buy the cheaper kite that may have had a few repairs and is very fatigued and you would have no clue about this. The majority of second hand kites I've seen newbies buy on the ads needed some tuning, repairs or adjustments just to fly right.
Older and weaker kites not only don't perform as well as newer kites in better condition but are much more likely to break if you crash them, even in the water. Yes newer kites are more expensive but they are stronger and will last you longer and are much less likely to break if you crash them hard.
The best advice I could give you is buy your first second hand kite from a shop who can give you advice, support and some form of warranty should something be really wrong with kite you purchased.
There are about 70 kite brands on the worldwide market, each of which make a least 1 or 2 models that would suit your needs, so it's hard to recommend specific brands. There are many websites who review kites, but almost all reviews are sponsored in one way or another so it's hard to get impartial advice. The good thing as a beginner is you could pretty much buy any all-around 12m kite that is in good condition and not more than 2-3 years old and never notice the difference between them.
hope this help. Happy Kiting,
Christian
