I highly recommend 63/37 over 60/40. I find it easer to work with.
I had the dubious distinction of being a "Certified Solder Operator"
for TI's Lubbock, TX plant (in, what, '82?). Although the training I
got there spoiled me forever in some ways, it's been invaluable over the
years.
One of the things that stuck was the "true purpose" of eutectic
solder. We always used 60/40 for original or initial soldering, and
eutectic for repairs or "oversolders". If you have a good iron and a
good eye (or, these days, good Optivisor), the flow-point difference
allows doing new work without disturbing old joints.
