"Obsolete?," Python exercises and skills?, "Passé? NO, the direct pythons, as they are called on CBS, (also known as "python tube" or "needle"), are far from being obsolete.
.
Why? Because they are a tube for removing foreign bodies that travel through the hose, especially today, a city rich in high-rise buildings. Modern buildings have a dry network, which theoretically Fire helps to drop water on the fire quickly.
.
Unfortunately experience tells us otherwise ...
Network dry, rigid pipe designed to carry water, though it also draws our papers, scale, sediment that can clog or reduce the discharge into a python Fog, is often more reliable to work with a solid running python, as live python, a sophisticated python Fog.
.
But you have a solid stream spout nozzle approx. 25 mm in diameter, similar to that of American firefighters, no problem! despised the German python used almost only in competitions, now may be a worthy ally when working with the dry network.
Removing the diffuser jet (half fog / direct) to clear the domestic product and also become the mouthpiece to extend flow capacity may grant a work buenisimo fires in height from 100 bpm to 400 bpm @ 5 bar with nozzles 9 to 16 mm in diameter.
.
Who said that all our modern fire-fighting tools are too expensive?
stacked nozzle 17 and 24 mm. 
direct German Python nozzle machined from 16 mm to give about 400 lpm to 5 bar with the possibility of eliminating waste and debris from the dry network.
Note the poor flow of the python Fog machine connected to the network dry on the fifth floor of a building, sent 11 bar pump pressure. When removing the spout rubbish and stones was found stuck on the grid inside the python.
