Jars

Does anybody have any experience/information/theories/ideas or
knowledge about running two jars in the same drillstring?

I understand that one set is right on top of the BHA (horizontal
section) and the other will be in the vertical part of the hole.

What are the operational considerations when running such a set up?
How are the jars cocked and fired?

Comments appreciated.
