A method, including selecting a first maximum radiofrequency (RF) power to be delivered by an electrode within a range of 70W- 100W, and selecting a second maximum RF power to be delivered by the electrode within a range of 20W - 60W. The method also includes selecting an allowable force on the electrode within a range of 5g - 50g, selecting a maximum allowable temperature, of tissue to be ablated, within a range of 55°C - 65°C, and selecting an irrigation rate for providing irrigation fluid to the electrode within a range of 8 - 45 ml/min. The method further includes performing an ablation of tissue using the selected values by initially using the first power, switching to the second power after a predefined time between 3s and 6s, and terminating the ablation after a total time for the ablation between 10s and 20s.
