I didn't take pictures (I know; I know), but last weekend I used a Prussick/ Cord Lock combo I wanted to share.
I use Prussiks to attach my tarp below the tarp ridgeline. I wrap about 6-10" of line for my Prussik around the ridgeline then tie the two loose dangling ends to my tarp ridgeline tie outs. I always found this tedious and awkward.
This weekend I looped my 10" piece around the ridgeline, but then instead of tieing the loose ends to the tarp, I just connected them with a cord lock. Very easy. I hope that makes sense without pics.
I ended up finding other applications. To go into porch mode I needed a prusik about 10 feet long. I tied one with extra line and then attached the end to the corner of my tarp with a cord lock. The 10 foot distance would normally be difficult to tighten the prussick to the correct tension. With the cord locks it was easy.
