PoE Kinetic Blast, Kinetic Bolt, Kinetic Bolt of Fragmentation 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. I like Minefield and makes it easier for targeting in all directions, but Barrage Support should be more damage. Might gem swap for bosses if I have a white socket at that p
