Hey guys, I currently have a Blackbird with the adjustable webbing. I really like it, but I also feel compelled to change things up so I made some whoopies with some 7/64 amsteel blue and got some Lash-It for the ridgeline. What's the best way to do the swap?

Also, when swapping the Lash-it for the ridgeline, what points do I need to measure for the 100" ridgeline? Is it from fixed loop to fixed loop, or do I have to account for the amount looped onto the new whoopies? Does that make sense?
