Hi Guys,
It's Alex back from work.
The Zensorflex weighs 1.2kg at 20ft you say John, well the 'Super-Lite' sections weigh only 360g at 20ft so this does equate to more than 3x the weight. Also I have measured the flex of both poles and compared with our 'Super-Lite' it is easily 3x as flexible, measured per degree of angle deviation at 20ft.
There, that's me being pedantic

For simple low level work as Alison said it is a great value little pole, but as a serious lightweight pole for commercial work it is never going to cut it. If you want to pick up cheap compatible sections then the Zensorflex number 3 section will perfectly fit the Super-Lite gooseneck, however if you want cheaper replacement carbon fibre sections you will need to stick with Maver Resolution sections 6-10. You may be able to pick these up second hand. Do not try to use the section Numbers 4 and 5 as these are far too fragile for window cleaning usage. For the top section you will need a Maver Super Taper section (code B4780 not the cheaper B3360) which I doubt you will find second-hand, also bear in mind that the Super-Lite top section you already have has been 'worked over' with carbon fibre reinforcement. There are many different Maver poles out there and not all are compatible with each other. For instance the Nebula pole you mention is a much cheaper (and heavier) pole, which would not perform half as well. The Grimreaper pole is also a cheaper pole (we do use these as extension sections sometimes as the 14.5m section is identical, bar labelling to our standard ones, the rest of the pole though is quite different)
There may be other makes of carbon poles out there that will fit your gooseneck but it will be trial and error finding them.
John.
We have never run anyone down for trying to produce their own 'cheapies', in fact recently we have helped several people on this forum with specialised parts that they have needed from us to complete their own converted fishing poles. We do however like to point out the real difference between the poles on the market, to those who are less familiar with these products. There is a very real performance difference between a pole that cost £250, but looks the same as one that costs £500. Our 'Super-Lite' sales whilst being quite impressive remain only a small percentage of our overall pole sales.
I have spent a long time researching many different brands and price brackets of Carbon poles for the 'Super-Lite project'. This has mainly been motivated, not by commercial interests, but by my desire to achieve the ultimate cleaning pole for my own commercial window cleaning firm.
I have personally bought many different poles available on the market and tested, weighed, assessed and tried them out. Currently we are sticking with our slightly expensive brand as it has the best balance of features for our window cleaning needs. However we are still striving to improve, we have 3 prototype poles from another major manufacturer that they have sent to us (at their own expense) to try out. I have also just purchased one of the latest Nanolith technology, Super Lithium, Carbon Fibre poles which is easily as stiff as the current pole but weighs about 450g less at 45ft, but with a retail price of nearly £800 for just the fishing pole which would reach 45ft I feel that it is 'too' much for anyone to consider as a cost effective pole.
I hope that this has helped you to understand the reason for our choice of product and why we charge our clients what we do.
