6061 vs 7075/7068 aluminium in bimetal weight distribution: weight vs durability, which one can be the lightest without sacrificing durability?

he knows i’m an engineer because he knows me. longevity is important because people… even pros… will hit a yoyo in the ground, sometimes a $500 yoyo on the first throw even if they’ve been playing for decades!!! if it was unplayable after that, that would be asinine to produce in any scale besides one…

good enough is for people that revel
in mediocrity, like ducking under the bar instead of raising it… and people that don’t care about the end users longevity of experience
