[HCARC] Solder Question

[Gary J - N5BAA]

Maybe an odd question from someone transitioning to crimp connectors, but I still need to solder the center pins on N connectors and solder in female N connectors as I replace so-239’s.  I have a source for some 40/60 tin to lead solder.  Is that better than 60/40 tin to lead??  Is there any other mix that is better than those??  Yes they are rosin core solder.
