I've used a SD788T with CL8 on a dynamic feature film, with gunshots, screams, and general dialogues. Dynamic range which 788 preamps provide is pretty much what is required for the type of content stated. The 688 or 664 have reboot issues plus the word around about the preamps not being the same for 6's as the 7's series.
There are screams towards the end, which were not scripted, plus the run and gun indi film setup. You can hear the limiter hitting peaks. Have a listen for a quick example on how the 788T preamps sound with limiters. The mic used is a mkh416 directly. https://www.youtube.com/watch?v=rBOEGgC7Jvo
