Use a slipknot to sling rock horns
A horn or spike of rock (aka “chicken head”), can sometimes be used as protection.
The problem: if you just loop the sling over the top, it's probably gonna lift off as you continue climbing.
Solution: make a slipknot and snug it down on the spike.
Tighten it well.
Practice tying slip knots one handed.
Consider a 120 cm sling.
If you think the sling may lift off, maybe clip some heavy gear to it.
A clove or girth hitch can work too. Try a few knot flavors and see what work for you.
