I took a look at the file last night. I did get some speed improvement taking each piece of the wrap and exporting it as a cmx, opening that cmx in a new file, removing the power clip and redoing the clip, and rebuilding a new file piece by piece.

I got the biggest speed gains by combining the grunge that was all one color and slicing off parts that were outside the clip in order to cut down the shear number of nodes.

That's about as far as I am in looking at it.so far.
