Hi Edward,
You should consider 2 rods for your application, you stated that the target fish is from 25kg to 50kg most of the time with the occasional 75kg.
the 75kg is a different animal and will put up the gear into the ultimate test, I am not putting any gear down or trying to divert you to a certain brand or rod but I don't believe that the Hot's 711 is adequate for the task, it might do the job on the big fish but who wants to be behind the rod for countless hours.
the shorter of a fight the better it is for the angler and the fish especially if you intend to practice catch and release.
Good luck.
