byRandom and byBusyChildren are both pretty good for the two server 
setup.

When you kill Apache one machine, backhand doesn't care.  It knows the 
machine existed and will continue to direct traffic to it, unless one 
of your rules says not to.  That is why the byAge rule exists and 
_should always_ come first in any rule set.  So, make sure you are 
using byAge and then byRandom and not just byRandom by itself.

byAge will make sure that servers you haven't heard from in a "while" 
are no longer eligible to be backhanded to.  The default is 5 seconds, 
but you can specify the max age you want -- see the docs.
