The Foils are super good. I'm 5'10 and 178 lbs and ski really hard all the time. The thrusters would be great for park but if you want a ski for everything the Foils are super sick and stiffer than the thrusters. Also try the CR labs they are super stiff and ski like a race ski. The Guns are also good and offer lots of flotation. check eh out at
