Nickle would not be as good of a conductor as copper so I would be reluctant to use them. Is it going to make a huge difference? In the grand scheme of things, probably not that big. But you are paying a big premium for them to sidegap them for you and to get the nickle coating.
I buy mine at Wal-Mart for a buck and a half each if that and spend a few minutes with the dremel and its all good.
