An object of the present invention is to provide a golf ball resin composition containing an ionomer resin with an excellent resilience and fluidity. Intelligent models can be defined that can be used by an application to discover actual relationship, dependency, or configuration data for components of an information processing system. One design utilizes many cylindrical surfaces with their axis parallel and their surfaces nearly in contact. For example, each wake inducing airfoil may comprise a rounded convex edge leading to straight tapered sides.
