I always thought some copper in the Brewery was a good thing. The German's and Belgian's seem to think so.

Thirded.  My 18-yr old copper IC is still going strong; if ever dies, I'll spring for a Hydra, but copper in the brewery (at least on brewday) I've never heard to be a negative.

 

That said, I do recall reading somewhere (quite a few years back) that letting the wort see copper during and/or after fermentation was a no-no, but not pre-fermentation.

if you asked the low oxygen people, you'd get a negative on the copper.  SS only for them.

yeah, something like that.  Ken may know more since he's been using LO methods

Same can be said for a long CFC. At some point the wort is going to be chilled as far as its going to be. No sense in buying a 40ft length when its already cooled at 20ft. 

I suppose you can run wort through faster though with a bigger cfc or pc

 

happy b-day too you old fart

Iron and copper ions are known to have a negative influence on beer flavour stability. Even concentrations of copper below 50 ppb are reported to cause damage in the final product.

My own experiences using Brewtan B to remove heavy metals and then removing a copper chiller in my brewery confirm that statement, however non-scientifically.
