Do You use 1 or 2 pins in a 3 piece take down besides the bolt?

most use one pin to my knowledge...

I have owned several 3 pieces, mostly Black Widows and RERs all had 2 pins and one bolt. I have had several Morrisons and a real nice Dryad Orion cant remember how many they used, but I have seen one pin used in takedowns. I see that Bob Lee uses 2 bolts and 1 pin?
