I have toyed with using ovals (and have a few). I use a scaffold knot to tie my rope to the quick link and like the delta for extra width. I have a fear that the oval could pull inside the scaffold knot which could make it untie. The delta can't have that happen, the oval might in some 1 in a million scenario.I gotta ask... Why are so many people choosing the Deltas over the standard oval quick links to girth hitch their rope tether to a tree? Bigger/bulkier, heavier, more expensive. I just can't wrap my head around it. What am I missing?
I have an oval, but remember reading a theory that a delta is harder to pull through a slipping/incorrectly tied knot than an oval. I have no idea if that's actually true and hope to never test it.
....edit: an easy way around this is to connect the quick link to a figure 8 on a bight and then figure out a way to keep the quick link on the rope so it can't fall off while climbing and making a move......wrapping the rope and then the quick link with a ranger band works
