PoE Shadow, Volatile Dead, Projectile builds

Playing around with some PoB's for Kinetic Bolt elemental stacking mines and with the latest POB update adding Kinetic Bolt, I've got a better idea of damage. Nothing too out of the ordinary for life miner builds with the exception of skipping Prodigal and Cruel Preparation branch for a cluster jewel with damage and life. Not sure about the KBolt supports.
