But I can use plain 30 by itself (without NR nickel whatcha-call-it) right BigBang, until I get my ready wires?
Not with your Ithaka. You need to join your resistance wire to Non-resistance wire. Check out igetcha69 Ithaka review to see how he joins with a Zapper (my preferred method) or Bishopheals single coil build on YT to get an idea of how to "manually" join your wires. This is the, "working the kinks out" that I mentioned in my previous post
