Ranking of the Ivies - in anticipation of Ivy Day

Forget T5 - it doesn't exist any more! This is where my agreement ends when compared with one of the rankings posted here earlier. Refined rankings below:

金藤     Harvard, Stanford, MIT 
準金藤  Princeton, Yale, UPenn, CalTech
銀藤     Columbia, Dartmouth, Duke, Chicago, Brown
準銀藤  Cornell, Vanderbilt, Northwestern, Johns Hopkins

Good luck, and may you choose wisely. hahaha
