Well, I've read that Volkl recommends a 1 deg. base/ 2 deg side edge for recreational skiing and 1/3 for racing. Most the replies I've read recommend a 1/3. I just tuned my 5* for 1/3, but, I'm in western PA where ice tends to be the norm. I was happy with mine at the factory tune of 1/2 and am just trying the 1/3 for the first time on the 5*(experimenting based on the recommendation of everybody else). If you already skied them, you know what the 1/2 is like. Try the 1/3 and decide which you prefer...that's what I'm doing.
