I rode the 2011 9m nomad several times. From low to highend. Coming from SB. Tried 2010 9m nomad only a few times. Couldnt really compare the lowend just yet. That said i never felt the lowend was a problem. Its only logical Nomad has less power compared to SB. To me the 9m is comparable to an 8m SB.
I was riding the new 9 yesterday in winds up to 35knots. Think that is my highend, which is good like the 2010. Estimate the lowend to be 17/18knots (85kg).
Talking twintip: To me the nomad still is a kite that likes to be ridden in the middle to upper range. There is a certain point where some ''button'' is switched and the thing turns in a beast. Sheet the bar out a little and it starts growling.
In lower to middle range I liked the fact that it felt very SB like. Very simular barfeel. Well workable for power. More forgiving after unhooking.
Have yet to try it in the waves.
