No6 sections are usually the one to break, approx. 8-10″ from the male end, No4’s also but that is the same for most poles I suppose. Just check how the sections fit together as Daiwa are well known for the sections coming apart when shipping, also look at the female ends and check how far the end of the section is from the point of the triangle – this will tell you if any of the ends have been trimmed back and how far.
I had a black Airity a few years back but never really got on with it, I went from a Garbolino G10 to the Airity and found it too soft and a bit bouncy for me so I sold it after 6 months.
Funnily enough though I have just sold my Garbolino Gmax1000 and M1 as I was now finding them too stiff ??? Funny how your preferences change as you change the places you fish and the type/size of fish you are fishing for.
These are my opinions, so can all the die hard Daiwa fanatics please not attack me. Cheers
