The Energy design of this ski means that it is equipped with sidewalls that encourage energy transfer, and thus control. This ski differs from the lower cost The Zero model in that it has an exceptionally large sidecut (157-127-146, as opposed to The Zero's 130-104-130 sidecut), which increases stability. This model differs from the identically priced Enforcer model in that the Enforcer model has an enforced titanium design (for increased responsiveness and durability), and a smaller sidecut (133-98-125 or 135-98-125, depending on the size). This ski differs from the higher cost Girish model in that the Girish model has a reinforced titanium design with a higher turn radius than the lower cost skis (26m for the 185cm. size, 29m for the 193cm. size). The Nordica Radict comes in a 185cm. size only.
