Maybe 4-5m off the ground. There I saw the average 8 knots and just beore I stayed upwind.
BS if you think, I talk experience with the info I had.
Fair enough...and i talk also from experience too...living in a LW world..Florida
I rode the Dyno 18M during the 'warm air" summer of 2011...with 2.5m extensions=27.5m lines
The LW TT board i used to test low end to stay upwind (avg.8kn) was a North Spike 153x47.5
Now you are on a board only "39cm" wide and only "128cm" short + you weigh 18 more kilos
To me a true average 8kn wind means that it never reaches 10kn
Avg.8kn is......7-8-9kn...or....6.5-7.5-8.5-9.5kn......and it should remain that way the whole time riding
Wind stations serve there purpose....but logic tells me that you would need 10.5kn on such board
Just my opinion of what wind power you would need in the kite...stations give their general idea
Avg.10.5kn is..9.5-10.5-11.5.....or 9.0-10.0-11.0-12.0kn of wind the whole time you are out
.........Once again my comments are entirely with all due respect
