SuperTip is great to have in your toolbox for those times you can't reach the surface needing cleaning with your lance, ladder is inconvenient and a manlift is out of the question.
We use 1/4" fittings and smaller hose for pressure washing. It is still high pressure, but not as much as the 3/8" fittings.
Your waterfed pole has never been so versatile as it is with Vic. pole tips. Acme style (broom threading) lets you use all kinds of tools you have used traditional poles for. With the Vic SuperTip and the right nozzles you can spray trees or rinse off buildings.
With the right accessories such as an MTM Hydro Foam Jet kit you can convert your pole into a vertical foaming cleaner.
