<p>Some questions about rope swings similar in size to the the <a href="https://www.youtube.com/watch?v=4B36Lr0Unp4" rel="nofollow">corona arch swing</a> which has an accompanying <a href="https://www.youtube.com/watch?v=Rm6pd-uvMeA" rel="nofollow">setup video</a>.</p>

<ul>
<li>Assuming you can avoid rope abrasion, do swings like this damage
climbing ropes? Swing goes straight into a pendulum with no/limited free fall.</li>
<li>The figure eights get very tight at the anchor. I've
heard people say you should loosen them, retie them, or cut them away
after several jumps. Any truth to this?</li>
<li>We set up a prussic
chord at the anchor. It attached just below the figure eight
knot that secured the jump line. This kept the weight
of the jump partially off the knots. Are there risks associated with
this - eg. can prussics weaken a system like this, or cut the rope?  </li>
<li>We also jumped onto a prussic (primary), with an atc below, with
overhand knot below that. We clipped the bite from the overhand knot
to our belay loop. We did this because we jumped with a backpack and
had to rapel to the ground after the swing completed. Slightly clustered, but we wanted to easily rapel after the jump was
completed. Any feedback on this setup?</li>
</ul>
