This is where I'm a little more knowledgeable, but I don't know the obscure classic lightweight fights of the 80s. Don't forget, it can't be a fight that's on the Fight City list. If you haven't checked it out, you should.
None of these four guys were greats or anything, but both Art Frias vs Claude Noel, and Harry Arroyo vs Terenece Ali were terrific wars. O'Grady-Kenty was a great war, and that one was fought on a much higher skill level than the aforementioned two.

Mancini Bramble 1 was a real good and tough fight. And Bramble had not gone many rounds before and few thought he could against a Mancini--and absorb round after round of punishment to get there. they were trading big shots for the first 5 rounds w/ no jabs. then Bramble started to switch up and he could do it almost as well as Hagler. When he turned southpaw, he'd jab and then land that big right hook. Very tough to continually absorb for Mancini and very confusing because like Hagler, Bramble would switch seamlessly. Tough tough fight and back when there were 15 rounders and this bout is another good example of the championship rounds==and which guy could dig deep in the late rounds.
