I used a 30ft bayersan, funnily enough my fingers would lock up (especially first thing in the morning) the diametre of pole is pretty big for a 30ft pole, and i think the clamps had a lot to do with it as well
I'll be honest, i wouldnt be surprised if one of the sections split before to long anyway (around the clamp) as the poles are so heavy and flexy!!
As said, go back to the DIY pole if it was better for you, i've mocked up a harris pole as a spare and its a cracking pole!! (Take off the bottom section of the bayersan and use it as an extension as and when you need it)
Otherwise i would look and a composite pole (huge difference from the bayersan : lighter/stiffer) or carbon fibre if you want to spend a bit more....
(I ended up going for the slx25 (carbon fibre) as the clx 27 was out of stock at the time)
If i remember rightly the price of a 30ft bayersan is around £100 and the clx27 (composite pole) is around £140 so not much price difference anyway but a huge difference...
(As an impartial ciu user i would like to add that other pole brands are available
)
