Thanks for the update !
FWIW, I ordered some OWB a while back and couldn't get them to spin freely enough for spin top use--seems like they are not all created equal. I i tried cleaning them and playing them to break 'em in, but they were sticky...Not saying this will be you experience, just saying.
The ones from S8 do not have this problem, so clearly some are good enough
Cheers. I cant wait to try these! Need to save a few bucks first.
