I use Severne Code Red 9.0 too, 2007 model (CR2).
Only for curiosity, what mast do you use with this sail? And, do you use recommended 30 cm tip extension?
I come from a 9.0 North Warp and my sensations is I feel CR2 really a light sail but a bit less powerful...
Sail profile is rather flat in mid to low section and when closing sail on the board in full speed, lower section of sail has a different cut, higher and less full than other race sail (it doesn't touch board deck hust for this reason).
I don't use 30 cm tip extension but a conventional extension in the bottom.
