Yes, Adrian, I agree.
The SxS/ ProRes workflow is very "light" so I don't usually use the Triplicator.
Highspeed or uncompressed work is different, as are some other camera workflows.
The addition of multiple cameras, lower compression, etc. will all put pressure on the pipeline and I think the Triplicator is a pretty cheap and easy way to deal with it.
Follow the rules though, or disaster lurks!
