Scott:

In Bob's email, he said that he uses "11110000" because he acts on a
key only after it's been pressed AND RELEASED... So "1111xxxx"
wouldn't work for him.

If it were me, though, I'd probably use "11111110" (or "xxx11110", if
four consecutive "1" samples were enough to guarantee a debounced
keypress), in order to lower the latency between the key-release and
the action.
