I like LMR-200 (a.k.a. LMR200). It is lightweight. It is much lower loss than RG-174 or LMR-100A. I’ve had zero durability problems with it, after a couple hundred SOTA activations.

The only down-side is that it is stiff, but I can coil it into a big circle and slide it into my backpack first, and it fits.

If I ever set up a home station, I’ll probably use LMR-400 because it is sligtly lower loss and the extra weight isn’t a problem at home. (It is stiff as the devil though.)
