Zusammenfassung:	A work string and method of performing a downhole operation is disclosed. The work string includes a first tool having a first ball seat configured to activate when a first activation pressure is applied to a plug seated at the first ball seat, and a second tool having a second ball seat configured to activate when a second activation pressure is applied to the plug when seated at the second ball seat, wherein the first activation pressure is different than the second activation pressure. A plug is dropped through a string in a wellbore. The first activation pressure is applied when the plug is at the first tool to activate the first tool. The second activation pressure is applied when the plug is at the second tool to activate the second tool.
