You are fight they wasnt from you.
You are also right about the wrong spec being sent out from the factory.
The trouble is that the first section is very lightweight , although it is strong , it is only strong at the right length, extend it all the way and put a bit of weight behind it and it could snap.
I mentioned about the overlap to the unmentioned supplier before they told me. the actual overlap on my pole was 8 in and it still snapped.
I would reccommend not extending the first section all the way if you have to put any weight behind the first section.
I still havent fixed my first section on my 30 footer , so i will take some photos over the weekend showing the problem and the repair.
I did not send the poles back as it was too much hassle for me, even though the supplier offered to replace them.
Saying that dont let my experience stop you buying one as they are very good poles and if yours snaps it is a very easy repair and you will end up with a no 1 section that is the right size for the pole weight.
