I work for myself, on my own.
Like Reflections said, the SLX is a solid,reliable workhorse.
If you are concerned about weight for whatever reason, then the Xtreme is excellent.
I've had the Xtreme 25' since it came out. Still on the original, but yes, I've replaced a section or two over the years. Mostly my fault really.
The 22' Xtreme is handy coz it has smaller collapsed height than the 25'. Just a thought.
Also, the dupont brush is fantastic. The natural bristles make light work of slug trails etc in comparison with the nylon only brushes.
