I need some input on a purchase decision...

I currently have a 10m Bandit III, and a Trax IV 134x39 board.
I am 178cm and approx 74kg, and not that experienced kitesurfer yet.

I live in Egmond aan Zee, where there almost always is quite some waves with the wind.

In the summer though, there is often a bit to little wind for the 10m, so I want like to get a second bigger kite. I borrowed an ozone 14m when I was on holiday in Egypt this autumn, and it was really fun. It was like driving a big Mercedes on a Sunday compared to my 10m Ferrari.

The question I cannot really answer before I try it, is: Do I get a 12m or 14m?
I really like the Bandit, so I will stay with f-one.

What I would like with the kite is to be able to go upwind in light wind, and just have a nice time surfing.

Input before I burn the cash very appreciated. 12 or 14m?? (Next year I will probably replace the 10m.)

With your weight you won't need a 14m kite in Holland.

12m might give you some extra low-end, but .... go for a nice waveboard and you will have much more fun with your 10m.

Sounds like the best plan. Especially the board is going to give you a lot more low end
