i would have done that to be honist if i had a gardner 25ft but my 25ft is a xline nano 25 and there extions are really heavy also upgraded the glamps to the phamtom ones as pole was looking very worn and clamps were allmost at full adjustment so ill just stick with the 25 till i kill it but its not wereing out since new clamps are on ?You could add an extension to your 25' pole to make it a 30' pole.

I had an Slx22 and an slx40 to begin with. I replaced the slx22 after 9 years of service with an slx27. Now I don't need to use the 40' pole as often.
We have a lot of new town houses with the main bedroom in the loft. My slx22 wasn't long enough to reach those windows where my 27' is.
