Just my opinion, but Airflo lines are definitely not as durable as they used to be. It’s too bad as I really like their lines and used to get 3-4 years out of them. For $100 a pop, you’d expect better durability.
My recent beach line experiences with Airflo 40+ Extreme Type 3 lines.
1. First line cranked not long after I got it. Airflo replaced it.
2. Replacement line started cracking shortly after I started using it. A hooked up humpy broke it in half.
3. I ordered another one. Glutton for punishment.

When I took it out of the box to spool it up, I found the core exposed through the outer coating just forward of the rear loop. I cut the loop off and added a new loop which held up to a sea lion that ate my coho.

I also ordered a SA Sonar Titan I/2/3 just in case the 40+ failed. I had this line before but sold it. I had a lot of tangling with the type 2 section. It probably had to do with the way I strip, so I decided to give it another try. I haven’t fished it yet.
One other type 3 line I tried and liked was the SA Sonar Stillwater Seamless Density. It also eventually cracked after less then year of use. Maybe not a good line in saltwater?
