jinky,
the widley used universal exel pole comes in four or five colours, you pay your 30,000 euros choose your colour and off you go,
so the exel poles are 99% identical as they are made in finland by exel.
glass fibre is a reasonably priced material as widly stocked.
carbon fibre / kevlar is expensive any way and due to the shortage largely due to the contract for airbus it means the cost of buying the material will be sky high,
hence you the customer pays more, there is no lets think of a figure and multiply it by (hhmmmmm ) 300% its down to manufactureing costs.
