In reply to Mike Hewitt:
A single strand of 5mm is at the lower end of acceptable strength for an anchor however used as a loop, on more than one piece and equalised it should be fine, assuming trad, why not just use ropes and ditch cordellette, pretty time consuming and pointless for most trad.
Direct belay why?, if you want to catch softly, use body weight and strenght to resist a fall or assist partner when it gets too steep then clip plate to your belay loop and crack on
If you want to escape the system regularly!!! or use a system designed for guides then consider cordellette and direct belay
You can't beat finishing a great pitch, slinging a spike, firing in a bomber wire/cam, hitching your ropes to the binders and shouting safe, quick and effective. ( I'll pass over the hrs of grovelling in the heather when placements don't appear)
PS I should have just draped the rope over the spike, quicker
