What do you use real or fake?

I have always used the fake rattling bag because they were easy to carry etc. I just got bored and played around with both real and fake ones and different sizes of real ones to compare the sounds.

The fake one sound similiar but they dont sound real. Maybe from a way away the might sound the same to a deer but who knows. I think I am going to start carrying a real set in my pack to use instead.
