I presently have my support lines tied to carabiners with bowline knots. I then clip the carabiners into slap straps.
Instead of a bowline, could I tie the support line to the carabiner with a tauntline hitch? That would allow me to make small adjustments to the sag by simply lessening the pressure on the support line and sliding the tauntline hitch up or down the support line.
I haven't seen anything like this mentioned on the forum so I'm wondering if there is something inherently unstable about my plan.
