In the UK it is either at the back of the cupboard or lead free, and effectively all
commercial new build is lead free.
A wireman assured me recently that mixing solder grades leads to ugly joints, so one must
keep a selection ;<)

I've never had great trouble soldering gull wing packages with lead free solder,
Some years ago I asked a professional board builder/repair person about switching to lead
free solder. Her advice was simple: "don't, not unless you are required
to". So I didn't. I keep a variety of real solder rolls around, preferably the
63/37 alloy.
