There is more to it, but here is the basics:

Chalav Stam Bshas Hadchak Proofs:

1)YD 4:5

2)Teshuva to Rabbi Weinfeld

Chalav Stam Meikear Hadin Proofs:

1)Rav Dovid Feinsein shlit”a (on the Matzav website (search “Matzav Rav Dovid Feinsein chalav yisroel”) it does say one should get chalav yisroel if it easy to get, but the terminology “bshas hadchak” is not there; it is more compatible with Rabbi Weinfeld’s teshuva)

Chalav Stam Meikar Hadin Rebuttals:

1a)YD 4:5 is specific case in specific circumstance

2a)Teshuva to Rabbi Weinfeld is not in the Igros
