@drbugatti 72 kg, 4.6 m2 top spin in the first two clips, and 5.9 score in third. I don't know about knots.
There is a bit of overlap with the 1110 I guess. Haven't sailed these back to back. When it's quiet then the 1260 is a sure thing, and when it's slightly windier then I have been happy with a 875 razor pro piuma kit which is nicer to ride in some conditions, especially if the water gets choppy. Some days it's difficult to decide which foil to take.
Here is one example with a 875. The 1260 would have worked better.
