Well, I would think that for a lot of people, the heyday for many fans would be the era that saw guys like Imanari, Sato, Gomi and Uno competing. Those guys are big names even now and the crowds were pretty big too. Of course, you see videos from that era posted and reposted on Youtube and I think many people's eyes, that's what they think of when they think of Combat Wrestling.
But hey, you are correct that I was mistaken about the original version of the rule-set not including catch-points. Years ago, when I was watching Combat Wrestling all the time and always reading up on the rule-set, I might have known that, but I must have forgotten. And in any event, I think it is very impressive what you are doing with Combat Wrestling.
At the same time, guys like Rumina Sato, Takefumi Hanai, Masakazu Imanari and Katsuya Toida were huge influences on me--and many others--as grapplers and as fans of grappling so of course the era they were competing in is going to be a Golden Era in my eyes. I also do think that the action in that era stands out as the pinnacle of what grappling can be aesthetically; even people that didn't know anything about grappling whom I showed that 2005 Combat Wrestling Anniversary DVD to were entertained and intrigued.
I agree that excitement is subjective, but given that the topic is which rule-set is most exciting or entertaining, I'm just giving my 2-cents.
