I've always found the Petzl catalogue a good source of technical advice. The impression that the techniques have been exhaustively tested during the R&D of their products has always made me err towards following the advice and changin my own methods to suit.
The techniques for tying off coils and tying yourself into the middle of a rope are on page 71. I'd be interested to know if anyone has used these methods before as they are completely different to anything I have come across or been taught. Can anyone think why they might give benefit over the more common techniques (e.g. coils follow by hitching a bight around the live rope and, for the middle, a rethreaded overhand)?
I realise that both techniques are sound and that there are horses for courses etc.
