More to the point.... how do you make a pole last 10 years ? thats some good going.
I can't speak for others but I ended up with a couple of SLX 25s and a single 30ft extension. I did stop using them as the thread came out the end of one (this was before section 1 had a clamp) and a couple of clamps broke on the other. I put them in the back of the lock up and started using a CLX 27 and a CLX 18 instead. Just never got around to fixing them.
Recently, I acquired a second-hand new-sized section 1 with clamp, so I've started using it with a gooseneck+xtreme brush. I have poles that are like Trig's broom - sections from God-knows-where, and it all works just fine.
You see, when a pole has expired, I keep the re-usable parts. I realise that some wait until just before they are worn and sell them on ebay but I just keep hold of parts instead. It's a long time since I bought a pole. I try to look after them, and I use external pole hose which reduces wear.
