The Hi-Power "Loop" yo-yo made by Shinwoo of Korea. The body shape is very similar to the Yomega Raider and used a size A bearing with a starburst molded into its response pad. The bearing was sandwiched between two small brass spacers. These spacers had two different usable ends. Depending on which end was against the bearing (or yo-yo body for that matter), you could adjust the responsiveness of the yo-yo. (See illustration of spacers on back of package)
