Buzzz Plastics Stability

Hi there.
I have a question about the different buzzz plastics. Which one i the most stable(all max weight)? Make a list with these (listed below)
Pro D Buzzz
X Buzzz
X Buzzz GT
ESP Buzzz
FLX Buzzz
Z Buzzz

Is there some colors that are more stable then others?

I think the Cryztal Z Buzzzes are the most overstable. With Buzzzes, generally the harder the plastic the more overstable they are. Look for ones that have a little dominess to them for overstability.
