Brass or Dacron transmission filter

I am swapping the pan on my 727 for one that I have put a temp. sensor and drain plug in. I am going to change the filter and check the bands while I am in there.

I was wondering which filter you guys run? I want to say that I read a while back that the brass filter should be used in performance applications and the Dacron should be used if you are running an aluminum drum. I was kind of confused by that so I figured I would ask around a little.

What filter would you guys run in a street/strip car without an aluminum drum?
