New electrical in walls & Ceilings

I am starting to finish my basement and have access to plenty of mc cable. Should I use what is free, or would it be easier in the long run to use romex?

 

Personally, if I had access to MC cable for free, I'd use it. Its a little "overkill" for residential work but if it's free, use it. Don't for get to use the anti short bushings.

 

Mc cable can be used if it is the right size and is not so old that it would not meet code today. It is a little harder to handle and requires special connectors at the boxes. It does have its good points but the bad points are the holes in your studs will have to be larger to get the cable through you have to put an insulator at each box connector normally it will take longer to use it and you must be very careful removing the outer sheath at the box so you do not damage the wires inside. The cost of 12/2 is not that much and might be more appropreate when it comes to the instalation speed.
