Hi Godswell,
That's fair. I understand the ramifications of applying the 'redistribute
connected'. I was just more curious as to how you would compare applying a
redistribution command to the other solutions provided in the context of
your statement "Why use a Scud missile when an AK45 will take care of the
problem?"
Thanks,
Sean
