hi sarah
we use carbon fibre universal , i make sell systems and sell poles .
as much as it pains me to say the ergo light just due to the price ,is the way forward at that height.
i borrowed a ergo light for the day just so i could comment and give advice , where it it took me 3 hours with standard carbon fibre 2 men swapping the ergo light managed by myself and it took 1 hour , i wont buy one on principle but i would recomend the face lift ergo light .as danniel is a fine manand the price comparrison is the same ,and as a company they use the poles themselves ,
i think you still have to be careful and thought ful when using it is not as robust as the universal but its lighter and at thet height if you cant pay for it after three months of budgeting then put up prices allways wack it on intrest free and usev job to pay for it
