You correctly point out that there are two separate issues here: the name and the death of the Balrog. I was above considering primarily the latter issue.

but the name Rog is to me a greater sticking piont than another balrog death.

And for me it is very much the opposite. But perhaps we should strive to keep the two issues separate and focus on one at a time.

Keep in mind that of all the balrogs slaughtered in the HII FoG only 3 make it to Q30. Glorfindels, Ecthelion's and Rog's.

Actually, no - Rog's name appears in Q30 but the compressed account says nothing of his exact deeds: "of the death of Rog without the walls" it says, and nothing more. But even if it did specify that Balrogs were slain there, Q30's conception of Balrogs is still quite far away from the 3/7 note's conception of them.
