Who is using what for air in their shop

Some time in the next couple of weeks I think I'll be in a position to get a bigazz compressor to stand in the corner, and I'll be piping air to a couple of places in my shop. I know it's a bad idea to use PVC s40 for this, but what about the s80? Will you still be pelted with needle sharp shards of polyvinyl chloride if you use it?

I called a place that does this professionally and was told they are now using copper pipe for most of their installations. Should be easy to install, but I've already learned there are different ratings on copper pipe and don't know what the differences are.

Bueller???
