I have always preferred a smooth cord end to eliminate tangles.
I usually used a clove hitch, or larks head, to tie the stakes to the lines, but this is so much better.
A loop, if the stakes pull out, from wind whip, usually results in the stake flying off, never to be found again.
Life's A Journey
It's not to arrive safely at the grave in a well preserved body,
But rather to skid in sideways, totally worn out, shouting,
Woo Hoo!....What a Ride!
