George, you are a master of understatement! And of course I completely
agree with you.
Nancy, among other things you need to consider the metals' affinity for
oxygen and dissolution into solder. I expect our metallurgical friend Dave
Hillman can provide you with the actual numbers for the above and other
interesting tidbits that we should keep in mind.

Nancy,
If I had a choice I'd rather solder to Pd than Ni.
