So I’m part of the yoyo bst and talk on Facebook and a user on there who owns his own company is making a bi metal and is in production and he just showed us on the page that he is designing a tri metal or quad metal if you count the axle aluminum body steel and brass rings and titanium axle
Technically any side Effect yoyo is a tri-metal. 6061 body, 7075 side effects and steel axle.
I was under the impression that more centre weight would work against the stability…?
Not when you land the string on one of the rims
