Agy80, that's my frustration! There are no credible sources yea or nay as research on a banned product is useless. Moreover, DSCR is silent on the issue, which by default allows the narrative the arrow throwers are hurling at DSCR to become accepted as 'truth'.
I guess it goes to the other fundamentals on DSCR, their history, track record, T/A, and about everything else we can drag in to make an informed decision.
