oh yeah, and they are deffinatly lighter, and more powerfull than any other sail, we can get the 6.3 to perform the same as a 7.5 and still be controllable and light, but you can also use it fully over powered and still get away with it. i could use the 5.8 in 23 knotts or i could use a 4.8 its really just a great all round sail, if you where to only have 1 sail i would go for a 5.5 superfreak just because you can rig it for high wind and low wind,
