[Milsurplus] What is your favorite solder?

[Bruce Gentry]

What solder do you prefer?  I got a couple rolls of Ersin Multicore SN60 
at a hamfest, and it is terrible. The flux doesn't seem to do much and 
it doesn't flow well at all. What are your favorites, something that has 
a really good flux that cuts through the crud and flows nicely on 
reasonably clean wires and connectors? Years ago, Ersin Multicore was 
one of the best. Unless wires or terminals were green with oxide, it cut 
through and made a perfect connection. Having to scrape everything shiny 
bright  before using the stuff I got  is a pain.  I tried some Tenma 
solder from Taiwan, and it's way better in every way than the Ersin SN60.
