I linked this list a few pages back. This is an "all-in" top modern variant list up to 100:

I like to keep this list tight with a fairly strict methodology so that it really does represent a top of the top variants, the blue chippers of the age, if you will. By applying the same set of standards, I feel we really can see what is the best of the best, and it tends to eliminate the outliers. I do agree that the chirping about the methodology is somewhat grating at times. Although it seems simple, I actually spent more time compiling the "rules" for the list than I did the books to put on it (that was the easy part). But as they say, you can't please all of the people all of the time.
