Modular Synth Panels

Time for me to get some new hookup wire.  I am down to  bits of 30ga solid telco untinned 
copper, 20 ga tinned solid and stranded. I need to re up on my supply. I like solid wire but I'm 
thinking it may not be the best for long term reliabilty. 

For coax I have a good bit of Belden rg174  26ga core ( i think).  I used to use something a 
little thinner and stiffer but I lost track of the number.

It would be nice to know what is use among my peers.
