i have two varieties of solder here, both 60/40 leaded and rosin-cored: .8mm and .5mm. the .8mm is great for general purpose usage while the .5 is great for surface mount components.
for flux, I have a couple bottles of Kester 951 and 186. the 186 is fairly aggressive and leaves behind some significant residue, while the 951 isn't nearly as aggressive and leaves behind nothing visible.
