What is the weight of the rds002 light. Is there a difference in weight depending op gripsize. I found this information on a tennissite. Unstrung Weight: 1/8 - 1/4 inch grip will weigh approximately 10.6 - 11.3 ounces. 3/8 inch grip and up will weigh approximately 11.3 - 12.0 ounces. Is this correct??
