For example using 1st layer haifu seamoon, 2nd layer falco tempo and 3rd dandoy bio booster or just mixing any different boosters. Did it feel different than using just one booster? I'm considering experimenting with the example given.
I was wondering if any manyfacturer has ever tried to make a blade with totally unsymmetric layers, such as hinoki top layer with alc / koto top layer with ZLC-type of blade composition? If not, why not?
