Replying to Ar6 or pipecleaner

   i got some 08 171 ar6's last year and they are the best ski i've ever had. anyways , for next year i  cant decide between a 176 ar6 or pipecleaner.  i'm leaning towards pipecleaners but am concerned after reading keystone park review where some testers reported instability when carving.   wondering if anyone who's skied pipe cleaners can give their opinion or opinions on preference from any one who has skied them both. i'll be using them for all moountain & park but iwon't be doing rails and i rarely ski powder
