When selecting a discus, consider the flight characteristics (amount of wobble, attitude and angle of release) and the athlete's ability to create rotary velocity (spin).
LOW SPIN- Center balanced (70% or less of the weight in the rim). Low spin discus are more controllable for the beginner and intermediate level athlete who does not yet have a high rotary velocity at release. Center balancing results in less wobble for a more aerodynamically sound flight.
HIGH SPIN- Rim balanced (71% or more weight in the rim). high spin discus are for advanced and elite throwers who can generate a high velocity at release. As the thrower's technique improves, a higher percentage of rim weight can then be used effectively.
