The X-Tels are on the whippy side as Sair said, but they are cheap and they are light. We have found that most customers who want a longer pole (27-34ft) for occasional work would rather have a cheap light pole when given a choice.
Those who use this height of pole a lot generally are prepared to pay more for a slighty stiffer pole (although not much lighter than the Glassfibre X-Tels)
It really does depend on your usage and priorities.
