Have used the Convergence in both salt-water and river applications. Good rod for the money.
Now however, I greatly prefer their "Technium" series for the chuck, and have replaced all the trolling rods with these. For the few sheckles more, the rod is superb in this application. 2 years now on a most of them, countless clients' hands, and no failures thus far speaks volumes IMHO.
Cheers,
