I have seen over 32 different pairings so I'm not gonna rank them all but I will do a top 8
1.Teal Wicks/Katie Rose Clarke
2.Stephanie J. Block/Annaleigh Ashford
3.Vicki Noon/Natalie Daradich
4.Marcie Dodd/Alli Mauzey
5.Nicole Parker/Alli Mauzey
6.Jackie Burns/Chandra Lee Schwartz
7.Dee Roscioli/Annaleigh Ashford
8.Dee Roscioli/Erin Mackey

I thought no one would ever touch my first pair Steph and Annaleigh but as soon as Teal and Katie Rose appeared onstage together I was like we have a winner. Their For Good is the best thing I have seen in almost 3yrs.

1. Stephanie J Block and Kendra Kassebaum
2. Jackie Burns and Chandra Lee Schwartz

4. Donna Vivino and Chandra Lee Schwartz

I don't remember all of them but these are the most recent and/or best pairs
Eden & Megan x5 (best pair ever)
Caissie and Megan x1 (only saw them on their last show but it was magic)
Teal and Natalie x2 (I wish more people got to see them. Natalie brought out a certain freshness in Teal)
Teal and Kendra (under rated, they where great together)
Eden and Emily x1 (it was Emily's last and truly fantastic chemistry)
Donna & Katie x1 (katie's last, chemistry was fantastic)
GAP
Anne and Natalie x1 (they worked well together.)
Teal and Laura x1 (they seemed like they had been working together for a long time, even though they really hadn't)

Donna & Chandra x1 ( I don't remember much but they had good chemistry)
Teal and Erin x1 (better then what people said, but not nearly as good as the other pairs I've seen. they did work together nice at certain parts, however)
Meredith and Marissa x1 (they worked together really well but they just didn't have that believable Elphaba/Glinda chemistry)
Donna & Stefanie x1 ( didn't like them together)
Caissie and Emily x.5 ( I heard they worked well together, I shouldn't judge as Caissie was so sick and I was just upset about her voice cracking left and right.)
Teal and Emily x.5 (same thing I was just so upset, I was sick, my tickets where terrible, caissie was sick, it just wasn't my day. I shouldn't judge)

I think I got all of them besides 1 or 2.
