Leave room for expansion.
If you use aluminum make sure the panel is tagged to accept it (and the new main breaker). Some are marked for copper only.
There really isn't a problem with aluminum for mains. Just use some NOOXID for the connections and check the lugs for tightness every once and so often.

The man breaker should not touch any AL. It's the lugs that touch the AL. Branch circuit breakers will have a wire connected to them.
