For me it was the 90's, ok i know their were people like bruno about but the top of the division included some all time greats, looking back then shows us how much of a mess the current weight class is in. 70's were great too but the 90's had more top class fighters rather than just the deadly trio that fought eachother over and over again until some one else emeged. The 50's rank 3rd IMO respectivly
looking forward to hearing your opinions
