I've done a lot of reading trying to decide between Bighorns and 2.0s. There doesn't seem to be a consensus. Most will say the originals are stronger (especially in the sidewalls) and therefore are the way to go. But then most everyone who has tried the 2.0s has nothing but good things to say about them as well. My 2 cents...if you ride isolated areas and need the extra piece of mind get the originals. If you don't tend to ride terrain that chews your tires, and you have the extra money (2.0s cost a bit more), get the 2.0s. HTH.
