Looks like you are a newbie in big tit buisness...lol.
I will try to help you.
Well in fact i am also not pretty sure about the cup size of Elizabeth and Minka but i think its sth around 3000 to 4000cc.
Beginning by the biggest ones following ladies had about 2000cc and more when they titfucked :
Zena Fulsom
(just one clip)
Allegra Cole
(About 4000cc)
Minka
Elizabeth Starr
Sabrina Sabrok
(3500cc, spanish model and pornstar)
Lolo Ferrari
(2800cc, weight of World record at that time)
Teddy Barrett
(about 3000cc)
Mistress Rhiannon
(about3000cc, just two hc clips with boyfriend)
Echo Valley
About 3000cc
Kristi Lovette
(old 3000cc size, camgirl, just few rare homemade clips)
Danielle Derek
(new tits with 2500cc)
Candy Charms
(2500cc, camgirl, made some hc clips in the past)
Crystal Strom
(About 2500cc, just one or two hc boygirl production)
Sophie Anderson

Ava Devine

Amy Anderssen

Yvette Bova

Sandra Star

Wendy Whoppers

Kayla Kleevage

Maxi Mounds

Plenty Uptopp

Olivia Villalba

Kirie GGG
Mandy Mountjoy

Tia Gun

I am Not sure anymore if two of those ladies did tf-action in their hc clips but i think so.
Perhaps i also forgot a lady. But even so i think it will take you some time to find all the titfuck clips of those women. I hope you got some vacation.
P.S.
Annina had 'just' a G-Cup. Her Boobs just look bigger because the are bolt-ons which fits perfectly to her body. But in fact they are pretty 'small'...lol.
