Subtle but important differences in discus design and weight distribution make a big difference in discus performance. A general rim weight guide follows:

Very High Spin (85-92% Rim Weight) - Advanced discus throwers who generate a lot of spin on the discus.
High Spin (75-80% Rim Weight) - Above average discus throwers who generate a little less spin than the advanced thrower.
Low Spin (70-75% Rim Weight) - Intermediate discus throwers who generate a moderate amount of spin on the discus.
Center Weighted (50-60% Rim Weight) - Beginning discus throwers who do not generate much spin on the discus.
