Ditto pretty much everything said above.
If you're into cooking (and given that you're looking at some very expensive cookware I'm assuming you are) then I might advise against the giant set of matching pots and pans anyway.
Certainly I recognize this may not work well with your wedding registry, but the fact remains that some makers and materials simply are better at certain cooking functions. A Le Creuset cast iron dutch oven or big griddle will out perform All Clad 80% of the time. A copper core stockpot is a waste of money at the All Clad level.
I'd suggest thinking about the pieces you'd like to have, and put those down. Ditto the comments on the copper core from All Clad, it's way over priced for what you get. And I'm no All Clad biggot, I've got about 14 pieces

I'm also not a fan of All Clad's non-stick. Perhaps they've improved it quite a bit since I bought mine, but I don't see the value in it over a much less expensive pan.
Regardless what you do, don't put it in the dishwashed or use a scrubber on the polished surface. Put a case of Barkeeper's Friend on the registry as well
