I think you are talking past me. You are correct in saying that judging the value of something is by nature, subjective. What I am saying is that objective judgments go into making determinations of value. It is an objective claim to say that, on the whole, cordovan will be more water resistant than full grain leather. That's what is missing. Whether that is worth it to you is your choice. I hope I've made myself clear because I can't think of any other way to say it.
