Stoked on my 2012 14m Rally. For me (215lbs), I'm out and upwind around 13mph, and plenty powered and having fun at 15mph. The kite turns fast and doesn't feel like a pig in the sky.
-in summary, the 14m kicks ass.
Also stoked on the 2012 10m Rally. The perfect middle kite for me (215lbs). I can get off my 14m early (17-18 mph) if i expect the wind to pick up, but am fine if it doesn't. I choose to ride the 10m until 30mph, but like all the Rallys, its range can go much higher if i needed it to.
-in summary, the 10m kicks ass too.
Picked up a 2012 8m to be my kite for 30mph and up. Have not been on it yet but i expect it to kick ass also. Will let you all know how it goes next time we have a nor'easter nuke session.
