Hi Jeff - here are a couple of other choices:

10Sn88Pb2Ag



1Sn97.5Pb1.5Ag



97Pb3Ag


Nothing wrong with you 90Pb10Sn either. Make sure you select a flux core
that has good thermal stability as your soldering temperatures are much
hotter than what you deal with when using the Sn63Pb37 alloy. Also consider
what the cleaning (or not cleaning) issues you may have to deal with.
