Mirroring a Series of Lofted Curves

Hi all,

I have created a series of curves from the image sampler. I am trying to copy and mirror these lofted curves and can’t seem to find a solution. As it stands, I’ve been baking the current output curves and mirroring them manually, but there must be a simpler way to resolve this issue within Grasshopper. I will post the current situation, the desired outcome, and the file as well. Thanks in advance!

P.S. Strictly speaking, TMatch should be used to cull the circles instead of relying on the desired curve to always be the first one:

Just what I was looking for. Thank you so much!

Here is another way to do it without circles and mirrors. Simpler!

I suspect you don’t need the A-B (Subtraction) component (and 0.9 slider either)?
