Rather than getting a new Xtreme and replacing the clamps straight away, why not, get some good use out of the pole and the clamps, then if you get wear problems, cut 2 inches off the section and replace with the same clamps? If you are going to replace the clamps, you may as well do it when the pole is worn, rather than when it's new! That's just crazy! Sounds like the guy who broke up a boat to build a raft!
Or
When my Xtreme started spinning (top 2 sections only) I used 2 part Araldite, which took me about 40 mins to do and left it over the weekend to cure. I think I did it 2 years ago and still going strong.
Or
For me, it's only the top 2 sections that wear (obviously the most used), so just replace those sections at 100 quid each.
It's the tools that we use.
I have an electrician friend with some seriously good tools. However, when he works on large building sites in London he buys the cheapest drills and tools he can get. I asked him why and he said everything on site gets knicked or goes 'walkies'! He just factors the price of the tools into the job.
Some tools don't last forever...that's life!
