I have a pair of 168cm Volkl Tigershark 10s "non-switched" w/Marker bindings. They have been skied very little and are in excellent shape. I am not sure of the radius but they will carve very quick, tight, turns and have the edge grip that Volkls are known for.
This ski has been a gold medal winner in all the ski magazine reviews since it came out.
The skis are at home and I can look tomorrow night and tell you the radius, more explicitly.
