Nah don't buy that lighter poles won't help with RSI.
A lighter pole will reduce the strain on joints and wrists.
As for hot water it's a tool. I know people have been 15 years WFP COLD! Still not hot.
Hot has it uses
I never said not buy a light pole...but the chase after lighter and lighter
poles for cleaning below 25ft whenthe difference in weight is incremental
but the cost isnt and their being a limit on beneft is pointless
The best way of reducing strain on wrists and joints is using the
tool correctly,as often as you can letting the whole body take the
strain rather than just your arms.
I agree hot is another tool..not essential but will have its uses
