Ring wraiths vs. Balrogs

[Aule]

I accept that a few Balrogs esp Gothmog could have been an equal to Saurons power. But in this case i would think that the Balrog in Moria would not have been as powerful.
It is an undisputable fact that the Balrogs were immensly powerful as they could beat down ungoliant that even their master Melkor was having trouble with.
The orcs had been in Moria for many hundreds of years and there is no statement by tolkien saying that the Orcs and Balrog had come into conflict in this entire time. Leading me to assume that this was because that the Balrog was aware of Sauron and was letting his troops be.
Although as Obloquy has said in the post above this, maybe the Balrog had no chance to fight the Orcs as they kept out of the Balrogs way completely out of fear.
Either is equally plausible in my opinion
