Which setting on the vari-nozzle is used for long-range reach and penetrating power?

Explanation:
A straight stream concentrates the water into a narrow, cohesive jet. This preserves momentum and travels farther before breaking up, giving you reach to attack the fire from a distance and the ability to penetrate through heat and smoke. The other settings disperse water into a wide spray or reduce/alter flow, which shortens range and lowers penetration. So for long-range reach and penetrating power, the straight stream is the best choice.
