Hello all,

Me and my girlfriend have recently invested in our first kit after a successful holiday in Puerto Rico (we live in NYC).
We enjoyed the community we met there and most of all we got hooked to the world of pleasure that kiting (or at least trying to) offers.
On our way back home we bought a used 2015 10m Airush Varial X as we thought it would be a good size to share in our quiver, 1 airush progression bar, 2 harnesses and a 2014 Axis Vanguard 139cm

She is 155lbs (70kg) and I am 190lbs (86kg). We are planning on practicing near by NYC area (NJ shore/Long Island) where, according to the different wind report I've been reading for the past couple of weeks, the wind tends to be below 15 knots

We went out only once with a shy 12/13 knots and as a beginner had issue getting on the board with the 10m.

The guys we met told me I should get a bigger kite while the 10 will probably be big enough for her to learn.

I would like to know your thoughts about buying a second kite.
Should we wait and play around more with the 10m or it might slow down my progression on low wind?
Should I go up for a 12, 14 or 17? (right now I am thinking more 14m)

Also I am thinking kite size as I feel I am losing speed quickly after getting up but is the board length an issue too (139cm) ?

Thanks in advance for your help!
