Are we talking race stock or shelf models?
I had the 2005 race stock P60 in 165 and now have the 2006 race stock Racetiger in 165. The P60 felt like a stiffer ski, a bit more difficult to turn. The Racetiger feels substantially softer, yet grippier. It is a much more damp ski, with less end-of-turn pop, quite glued to the snow. It is not a heavy feeling ski, yet it feels heavier than the P60.
