Like another BDer I but 65lb MC and stopped at 700 yards with plenty of room left. Fished a 60lb fluro top on a Calstar 770 xh in a recent PV trip and the reel performed very well. 50lb plus rooster fish and tuna had zero chance with its smooth drag and rediculous capacity of MC.
I filled it with 80lb Hollow Phenix Hydrabraid. Matched with a 7802XH Hybrid rail rod. I fished a short 6-10ft piece of 60lb Premier for the local bluefin last summer. I went 4/4 on fish up to 65lbs, averaging 15-20mins to gaff.
