than get a single SONET/WDM protected 10G Wave you are better off
getting two unprotected 10G waves and plugging them into your

That really depends.  Two unprotected circuits are going to cost you
twice as much.

It doesn't depend. With layer 2 protection you still have single points of failure. I.e., if your line card catches on fire you're dead in the water. With two independent unprotected circuits the other circuit is still there and the routing protocols take care of the details.
