CLX will be awful to use at those heights...i would say an slx would be the minimum.
Yep, the clx are too flexible at those reaches.
Carbon is the way to go and the slx 30 would suit as an everyday pole.
Again agree with prices, its very demographic. Within doncaster there is such scope on prices between all the window cleaners. I have several villages where £10 min is accepted but 5 miles out and £15 is the min for a two bed semi.
If you are starting on your own, then gaining all your quotes is very good, especially if you feel the price is competitive for your needs. However after a period of time, you ideally want to gain about 70% of your quotes because if nobody questions your price, it could be a sign of being too competitive.
