I remember that every fall the Duncan demo team would come to our school. One year they would demonstrate yo-yo’s and the next year it would be tops. This was in the 70’s. The wooden tops were the best. You would have to buy special replacement tips for the tops because they would wear out on the asphalt. I still look for those tops. I see Duncan makes still makes yo-yos, but I haven’t seen the tops in 20 years. Too bad.
