I found my diamine Eau De Nil satisfied similar colour palate needs it writes almost as nice for those who may want something cheaper
I've done the popular Iroshizuku ink sample from the goulets and it is hard to find any flaws with them, there are about ten colours I want to have now and over time will add them in
I've resorted to Diamine to find reasonably priced alternatives to the Iroshizuku inks, but I do like my bottle of Shin-ryoku. It'll probably be my only purchase from that line of inks, though.
