About VIP Air:
The Air Technology allows Westside Discs to lower the weight on both the flight plate and the rim. In the rim, effort has been put into guiding the majority of Air towards the center. This is done to give better impact resistance to the edge and bottom of the rim. As always lighter weights means a little bit less stability in the wind so expect the Air models to behave accordingly.
