I'm thinking to buy an okuma abf 90 or a penn fierce 8000. Both reels are great but one and the other are missing something I really like. The okuma reel is a bait runner but its not a full metal body construction(its what I think I read while researching, it seems to be graphite). The penn is vice versa. So my "main" question is, how much longer would the penn withstand a beating against the okuma if I was to haul in a giant sturgeon?????? Any answer would help
