Time for a refresher on the manuals then...
Guys, my question wasn't really about whether if it was in the manual, as it clearly is - the picture I posted is taken from the manual.
It was more for me to gauge how many people know about it as I've seen many people doing it with a separate krab on the mallion. I found it worrying that many people do still so it that way. A lad who is fairly new to SRT, initially asked the question as he too had seen individuals doing it that way too.
It has sparked off a debate on the DCC Facebook page with some cavers even defending the method.
