I've always taken a 9m and 12m there and I'm the same size as you. If I could take only one then I would go with a 10m Crossbow since it has a big range. January is a lighter wind month so I would want my 12 or more, mid-summer on the bigger days I'm finding my 9 is too big, so I'm going to add a 6 or 7.
The new Cabrinha kites for 2014 will be fully announced in August so you should be able to get some good deals on prior model years in January. You might think about waiting till you get there and can check all the deals on Maui at the local shops and schools and you can still go online.
Well I learned on the catalyst 2013. I wouldn't mind purchasing a new kite if there is any benefit to it. Everyone has told me to always purchase new lines. though.
Would there be any benefit for 2014? I know its hard to find the catalyst used
Ozone distributor/ a store is located in Corpus Christi tx from what I have been told. I live in Houston, so I wouldn't mind making a drive over there to take a look.
