Hey guys like an idiot I tied a knot in my amsteel hammock suspension....I should have kknown better, but I went ahead and hung in it and now that knot is hella tight. Any ideas for how to get it out, its just a basic overhand knot (i think thats what its called).

Also, basically I accidently ordered the amsteele suspension instead of the whoopie slings. I think it is 1/8th amsteele, can that be set up using descending rings? I heard that it weakens the rope but in a pinch would I be ok to do that for a night you think? Luckily Arrowheadequipment is awesome and are rushing me the slings, my back up plan is the rings.
