I think I would consider Harada an overall better fighter than Saldivar, so he should at least be in the 50th spot. I know you said that in your opinion lower weight fighters don't usually have strong enough competition, in fact you said this when referring to Canto who competed in the strongest flyweight era. I think Harada should be able to get past that barrier considering he beat your #37th pick and arguably the greatest boxer of all time in that division twice if that's not strong enough competition then I'm not sure what is.
