Get a cup of tea and read this:

Then decide from there. The copper gaskets aren't great in our experience as there's no raised sealing points - we prefer our version of the BW750, as this has all of the latest revisions and seems to last well.
We have a couple of race teams giving them a battering - and so far no failures.!
