Interesting. It's a unique metric that I can see being nothing for some people but being a real hassle for others. Good to know. One more reason to try before you buy I suppose! I didn't feel this at all with the BRMs either. I wonder if it's just the specific knots, cord, or sheer quantity on some designs?
I own BRMs kanahas 2,5 m, 4m and 5.5 m. And naish 3m and 4m (very similar to the f-one honestly).
The 5.5 m can go from 8 knt and feels well powered at 10-12 knt. From 15 and more is a truck.
What I learned:
-A big parawing must be of a light material, because the issue is not going up or starting, there is plenty of pull in the 5 meters (same as a wing or more). But giving is very hard in heavy parawings. The 5.5 meters kanaha gives better in 10 knt than the 4m naish in 15 knt. Weight slows things down and decreases reactiveness.
-A big parawing requires a higher aspect ratio as material tends to fold between the A, B, and C lines; plus, definitely no folding tips in gusts.
Now all parawing that I tested works well in 3 and 4 meters, and in the 15 to 25 knt range. Challenges are at the top and bottom end, so I would say that selecting different brands should not be discarded at this point looking for the perfect combination of weight and AR.
