Default RE: North Warp 2007

you've already the answer.
The 9,9 has a big draft and is best tuned to power you up in very light air and the 10 has a more thin profile to propulse you towards the strong gust when fully powered on your formula gear.There's some difference in leading edge too as well as leech tension.Draft position is another issue...
