Screen hardstatus

Screen is one of the best programs ever made for linux. This is my current hardstatus line, always a work in progress. My .screenrc:

backtick 1 1 1 $HOME/.screen_custom/sys_status.sh

hardstatus on
hardstatus alwayslastline
hardstatus string '%{= kg}[ %{y}%H %{g}][%= %{=kw}%?%-Lw%?%{y}(%{W}%n*%f%t%?(%u)%?%{y})%{g}%?%+Lw%?%?%= %{g}][%{y}%Y-%m-%d %{W}%c %{g}]'
caption always "%{wK} %1`"

As can be seen in the first line, it includes a script I've placed in a custom folder:

#!/bin/sh
uptime | sed 's/.*average: //'

Although, it's a bit redundant with multiple windows open.

I also need to see if there's a way to put the -H 1000000 option I like to use in my .screenrc instead of specifying it when being invoked.
