Yes on the above recs.
For me, I found the Radio Shack 18 ga is surprisingly good. For some experimenting, you might want to try their 16 ga on the woofer and the 18 on the tweeter.
Also, I'm not sure why but the 18 sounds better than the 12 ga. I have some guesses (like the thinner dielectric) but I don't listen to guesses or theories. Just try it.
