Hi Pete,
I work at OR headquarters in Victoria, BC.
I had my first session on a Storm 5m on Friday afternoon. I weigh 215lbs (97kg) and was in 28-44 knot winds. There were 4 us out on the Storm kite and we ranged from 140lbs (63kg) to a couple of us in the 215lbs range.
The kite is responsive but it is not a bumblebee in the sky as compared to most small kites that I flown.
In the lulls I was able to stay upwind and cruise without having to work the kite too much. When it was juiced up it, I was having a really good time! The kite is stable, predictable, and easy to fly.
It flies as advertised.
