Grunt or Bleat when rattling?

[ne_hunter]

What is better to use when you are rattling, buck grunts or doe bleats, or a combination of rattling, grunts, and bleats

I actually had success this past weekend doing rattling, grunting and bleating.  I was able to call in two different bucks on different properties within a couple hours of each other.  When I rattle I try to make it sound like there is a hot doe with bucks fighting over her.  I must say that it is very exciting when you can call them in!!!

Yeah I'm not too sure when to use the grunts, bleats, or rattling and in what combination.
