Far as I'm concerned, the price of the tools, and the
lack of rigidity of the tubing are the main reasons for CPVC
being seen as more suited.
For applications such as radiant heating, being installed by
the pros, it seems like a natural.
Here's a site
http://www.pexconnection.com/products.php?catID=124
showing crimping tools that cost nearly or over a hundred dollars because
of their limited application and utilization. Seems to me that they should
give you the tool when you ask for it with an order of over 500 feet of
tubing.

As to the question, my vote is for copper. And Copper-Bond.

Doesn't it require some expensive tools to make the joints? From what
little reading I have done on it it sounds like a good to excellent
system but I see nothing in it to recommend it over CPVC other than it
being flexible for easy old construction rehab.
