Not quite the same, but......
When i first started n knew nothing about poles, i started with a carbon pole from purefreedom and a phoenix hybrid pole. I used the first section of the phoenix for something, cant think what as i never liked the hybrid compared to full carbon. I think i got the 27ft pole.
Anyways Ive started to use this pole with my trolley and its not bad without the flimsy first pole in. So i ordered the "e" section pole which came today
This has got me thinking, as I also added another section to my slx and made it an slx 27 a while ago.
To stop some of these poles being a little wippy due to the smaller diameter of the first poles, is it worth buying an extra base poles to replace the first pole, so you retain the length of a pole without too much flex. Or to replace the middle pole which contributes to the flex of a pole at such a length with an extreme perhaps?
