Would you end PEX with Copper ?

I am changing all main runs which are 1/2 inch Cu to 3/4 PEX...... I could run PEX all the way from the start to the end (would reduce to 1/2 inch PEX right before outlets)....however, was wondering if it wouldn't be better to actually leave the current Copper piping about 6 to 12 inches from the faucets / toilets etc... and just connect via reducer to 3/4 PEX ?

Any recommendations ?
Assuming all things equal....would you just remove all Copper ?

What's the reason for all those changes? If you are going to use Pex, use it all the way. Otherwise, I don't see the advantage.

Only need main runs with 3/4" PEX then 1/2" supplyes.
Where it comes out of the sheet rock use PEX stub outs.

Depending on the age of the plumbing system, you may have old valves at the fixtures that could use an upgrade to newer 1/4 turn ball valves.
