that much depends on the board You use and the type of kite YouÃƒâ€šÃ‚Â´d buy.
You are perfectly right with the couterproductive size. While teaching and really having to milk the light wind days i have found out that the 6 mÃƒâ€šÃ‚Â² was the size to go. These were the last ones to drop off the sky with me as well as with the students. Larger kites fell off the sky due to a lack of turning speed where smaller kites fell off due to the higher influence of the same thick kite lines (parasitic drag) and lower Reynolds numbers i.e. lower aerodynamic performance.
With 67 kg and a 12 mÃƒâ€šÃ‚Â² You wonÃƒâ€šÃ‚Â´t gain much with a LEI but You can still go for a larger board and/or a Foil - especially a 15 mÃƒâ€šÃ‚Â² SPEEDÃƒâ€šÃ‚Â² with light weight fabric (SAÃƒâ€šÃ‚Â² 19 mÃƒâ€šÃ‚Â² is too large for a 67 kg rider and the 12 mÃƒâ€šÃ‚Â² will not be that much more powerful than the ONE).
I am ~65 kg and i rode up to 20 mÃƒâ€šÃ‚Â² c shapes and still own a 16 (but i donÃƒâ€šÃ‚Â´t use it and i wouldnÃƒâ€šÃ‚Â´t buy larger than 15 now), rode bows up to 14 mÃƒâ€šÃ‚Â² (would buy up to 12 mÃƒâ€šÃ‚Â²) and foils up to 21 mÃƒâ€šÃ‚Â² (thinking about buying SPEED 15 but not any larger).
With inflatable kites YouÃƒâ€šÃ‚Â´ll need some 7-8 knots (some need 9 knots for the launch) but with a lightweight foil You can go in 6-7 knots (You donÃƒâ€šÃ‚Â´t want to loose Your board and relaunch in deep water till itÃƒâ€šÃ‚Â´s convenient 8 knots
Best to get a really wide wind range is to have a large high performing foil (where literally nothing else works), than take a medium size LEI (better turning speed), then add whatever You prefer for strong wind.
