I get years from my wfp's. I re laquer them. The number 1 section of my Slx 25 snapped near the top a couple of years ago, cut each section a little shorter and kept as a spare, approx 21 ft now and as the most worn sections have been cut off, it's got a new lease of life. I've also made a short pole in the past for washing the van/ bungalows from worn poles, even a telescopic gopro stick.
Some would call me a skin flint but considering what these carbon poles cost I re purpose them where I can. They don't biodegrade in landfill.
