Modular Synth Panels

Question:

What is the best  and what is the smallest shielded hook up wire ? 

I am almost out and am wondering aloud if there is something smaller 

I have been using two types both unmarked both feel like Belden (stiff) 1/8", one a little less 
so (smaller, waxy, stiff) 7/64".   I don't remember the cat numbers a thousand feet back.
