I started throwing about 2 months ago, with a Magicyoyo T5, and after a month got a YYF Edge (not out of necessity but because I had the money for it). I also recently purchased a YYF Horizon.
I now have a total of 3 yoyos and 5 bearings, 1 KK steel ball bearing, 2 Centertrac steel bearings, and 2 ceramic bearings.
When I first got the Edge I did a timed basic throw, and the yoyo stopped spinning after 4 minutes and 45 seconds. While actually doing tricks I was able to keep it spinning for about two minutes. I did this test again yesterday, and the yoyo span for about 90 seconds before stopping, and after 30 seconds during play.
This seems to have happened with the KK steel bearing, the older of the center trac bearings and both ceramic bearings. (Roughly the same reduction in spintime), I lubed the bearings properly, and I have tried several times to clean them in mineral spirits, but with no change to be had.
I realize that this is usually a problem of keeping the yoyo in the same plane during play, but that doesn’t really explain the reduced spin time outside of active play ???
Any input would be appreciated.
P.S. In case it’s relevant, I was doing the first half of kamikaze using the Edge. It’ll get through the first half, but only part way through the second.
