A little bit about the gardiners exteme at height
On the extreme 47 pole there is very little flex if any, u can add the hm single extensions taking it up to 72 pole ( I only have 5 singles ) and still there is very little flex and great to work with.
Add the triple extension taking it to 85 ft and the flex is unreal, the pole becomes a bow making it hard to work with.
I think this is down to the weight in the triple tho.
working with the singles at height is great and in hindsight would not of mixed them with the triple.
But add the triple alone to the pole give u a 60 ft pole with very little flex and still easy to control, it just becomes an issue when mixing singles with the triple
