60 is too old.
I like your Luttig, Roberts and the one they call Scaltio (Alito), plus Pyror, and Janice Rogers Brown. I am certain POTUS is going for the gold and that he's been waiting for this fight.
My point with Ted, is that 60 isn't TOO old, but POTUS has other younger ones in his arsenal. The appointments will be a huge part of his legacy and he's not going to blow it.
