The Loudness Police will be after me, but if 'loud' is the son du jour I clip the TC6000 a bit before Pro-L, and that probably achieves a similar result to Ben Subvert. I've found hard-clipping the TC to be quite effective, don't know if this is some function of its 48bit processing but it sounds as good as one could hope.
FWIW, Pro-L hasn't replaced Ozone's loudness maximizer for me, but is another good tool in the box. I use them each about half the time depending on which is working best for the material.
