13 months on and to avoid a long explanation I will keep this as simple as possible. The high reach carbon fibre are excellent for up to 75ft. But may eventually wear and are best kept for the high work. I now reccomend that everyone make and use a 26ft pole using the Zensorflex £20 pole and combine it with the Ron Thompson Reload pole £50. The reason is although there is a bit of flex with the No3 section, if you use the No4 Zensorflex you will have an indestructible top section and a lot less flex. (pic to come) in this temporary pic you do not need the unger elbow the No4 section simply push fits intothe base of the swivel loc adjustable base. Fast on off for hand use.
The No3 Zensorflex section is used for fitting an unger elbow when you want it.(as described above) (pic)
You can then experience a modular pole that is cheap and tough enough to withstand rough service use.
I suggest you use 4mmID silicon/pvc pole hose then connect to a 6mm van/trolley hose.
For going higher than 25ftish you can then use the top sections of the above two poles to fit on or around section 5 of ANY 16m carbon fibre pole although you will not beat quality at the £249 price of the CFS 16m
.
So to end. My ideal pole is actually a combination of all three for toughness quality and price. Plus spares are readily available
