WTF, Zeus or Columbus?

[lowend]

So, I can't get a straight answer as to what (if any) is the difference between Zeus and Columbus hops. As far as I KNEW, they were exactly the same thing, but now I'm hearing that they are two different (but similar) varieties. Does anyone have anything to add? I'm trying to recreate a beer that I made with Zeus hops, but I can only get my hands on some Columbus hops. What should I do?

Columbus, Tomahawk, Zeus are all the same.

I asked Ralph Olsen about it and he said that DNA testing has shown them to be genetically identical. If Ralph says it, I believe it.
