I keep four poles in my van. An extreme 44, slx 30, slx 25 and extreme 22. Use to use slx 25 on most houses going and only in the last month have I started using extreme 22 on smaller houses where possible as I clean a lot of Edwardian and Victorian properties which require a 25 or 30. Since using extreme 22 I find it so much quicker and lighter than normal 25, wish I'd done it earlier as easily compensate for extra cost of pole health wise and earnings. Started off using Hybrid poles similar to clx but they wear down too quick and would have to keep adjusting clamps with a screwdriver and they whipped like mad and would take a lot of excess energy to control the whipping action just to clean the windows. Only good thing about hybrid poles is they are better insulators so in theory safer to work with if thunderstorms are predicted. I was up a ladder one time when a thunderstorm struck the big tree four feet behind me with a lightning bolt, slid down the ladder and left it, went home and came back the next day for my ladder.
