bigbillybass, that reel is a little light I think for what you want. In that Penn line, they are rated as follows:
4/0 475yds. 30 lb. test
6/0 475yds. 50 lb. test
9/0 675 yds. 50lb. test
The 6/0 is a good reel but I would not spool it with 80 lb., it's a little light for that. The 9/0 you can spool with 80 lb. but the reel is a little bulky.
Without getting into the International's,
Penn makes a 15KG, 2 speed which holds 660 yds. 30 lb. which you could spool with 50 lb. Beyond that and I think you are into the International's.
Remember now that these are Peen Reels, they are for men who drink their coffee black and like their fish big. I'm sure you will hear from others on this with different reel brand recommendations.
