My first one lasted 4 years of daily abuse! I replaced it out of mercy rather than need.
I think my current one is about 18 months old, it gets the same daily abuse & is going strong with plenty of life left in it yet!
The SLX is worth every penny above the CLX & more. It's lighter, stiffer & should also last longer.
I guarantee you this- buy one & I bet you never buy another lesser pole!
