Hi David
There was a thread on this on rc.com about using the 8 to dynamically equalise anchors which I pull tested and not suprisingly the equalisation was appalling as the friction was so high. As to whether you can melt the knot if one anchor fails is something to be drop tested, I shall try to include it in the next lot I do, hopefully sometime next week.
For equalisation better anyway was to tie a normal loop using a fig 8 and clip a krab into the upper bends of the knot, clip the loop into both anchors and then between them into the krab.
