Curve selection with near point

[blackchicken]

Hello

I`m searching for most effective way how to select (pair together) only one nearest curve of specific scattered point. I have T-pose baked curves  (Fur curves, million of points) and I need to simulate them. I`m separating longest lines, where sim will be visible, then I`m scattering points on given surface (skin) with scatter relax, so I have nice, even distribution of points. Now, I cant find nice way, how to separate only one curve with nearest distance to specific scattered point.  In the end Ill have same number of curves as my scattered points. Little scene attached.

Also second step will be most efficient way how to transfer simulated guides back to baked Hi-res furs. Point deform is quick way but I`m looking for something super efficient. Don`t need extra details with transferring per guide, I`m looking for speed. Point cloud with radius with blending position is best bet? What do you think?

Thanks a lot for ideas.

 Thanks a lot Tomas, that`s exactly what I`m looking for. I was lost in different loops but I knew there`s some really simple solution, like that one.
