Yes, they are 26-27 meter, my bars with "normal" foillines, which in my world are the "short" lines then.
For non foiling (waveboards) I use 22 meter lines/bar, but never for foiling.
In above conditions today I would normally have chosen at least a 9 m2 kite, or a 10 if I had one - but if I know there are lulls and gusts I use 30 m lines with the 9 m2 so I dont get "caught".
With my "normal" wings.
This WaveXL wing is 790 cm2 and lifting well too, was amazed how low it could go and still turn fast because it is swept and low AR.
It wont win any speed or upwind contests of course, but does not matter really as not the purpose.
Thus my 8 m2 worked just fine, which amazed me somewhat as difficult to waterstart as said
The reason I took such a small kite today was because the forecast said the wind should pick up (but it didnt, not till it started to rain, after I had stopped)
So yes 28 m lines with your Carver wing in these winds are just great, you get a huge windrange out of it and much better carving IMO, pleasant pull all the way through any turns now
Whereas with 20 m the power will be there for a short time only, and then dissapear and there is "nothing" left
But individual, some prefer shorter lines in this wind.
