Once seeing my ally performing Wind: Rasenga, excited I must say, I knead my water chakra in my palm by performing the handseals and apply shape manipulation to materialise it in the form of a vortex. After that I bring my palm near the Wind rasengan. Then, a combination of the two technique would occur, resulting into a massive water vortex, plus devasting wind and raw chakra. This combo is then directed to the firestorm, easily washing it away and extinguishing it.
So this technique is a very good one, which requires to have mastery over Rasengan and as well as water. This will result in a combo of wind and water, which can defeat any fire technique with ease. As you need ally, you cannot perform this technique alone, unless you have yin yang. So this said, you can create a devasting combo using those two techniques. It's very quick to use, as shown in the anime, which stopped Kakuzu's fire in matter of seconds. The range is normal too, works most of times. Doesnt require water source, imporantly to add. I guess this is it.
