Id say Jupiter asia 3 is better for a 8-80 replacement, I like it more on the BH. BD 5 is the proper alternative from Yinhe
And I would add Loki Arthur China (boosted though), Xiom Vega China, and Bluegrip C2 here Not perfect alternatives, all different but good. There are more though!
I love the 729 battle 2 prov blue sponge, but it feels very heavy on the Harimoto ALC blade. With my wrist injury, I really feel the weight. Is there a lighter alternative? Or would adding some weight to the handle help balance it out?
