I rode the 9m One today - here is the graph - http://www.ikitesurf.com/windandwhere.iws?regionID=138&siteID=224 .
This sensor is approx 20% high, and I was riding between about 1:30 and 3:00. I’m 145-150 and was really impressed with the low end of the kite. I have a 12 One also, and would normally have put it up but I really wanted to break in the 9M. Conditions were side-onshore with chest to head high shorebreak. I had no problem blasting upwind and easily planed through the holes on my Mako board.
This kite is pure magic - super fast, stable, turns on the dime, and VERY low bar pressure, but I knew exactly where the kite was at all times if I went down in the surf. If you are a lightweight, ride a surfboard, or live in a place that gets some wind, this is the One to have.
