Thank you for the review. In the end seems like the Fin-Nor Off-Shore are a better choice.
If you want to try a not so expensive reel with dual drag, high density gears and all metal construction you can get the new Okuma Salina.
The size 40 max drag is over 30lbs and the size 80 is over 60lbs (

).
I had the CABO PT40, same drag curve as the one you describe, don't know about the CABO PT80 though.
