Incoming call, Bluetooth on.

Have a better battery life by using this rule. It will start Bluetooth whenever you are receiving a call, if your Bluetooth headset is in proximity it will connect automatically (depends on model of headset). And whenever you turn off the headset it will turn off the Bluetooth. Works great with Jabra Supreme. If you use a different headset and want to make it more convenient just change end trigger to "All ending phone calls" and Bluetooth will be turned off every time you end a call.
