I've been to a few shows over last few years big and small in UK but you really can't beat a decent small hall show. Went to the first pro show in Plymouth for a few years at the weekend, there were 8 or 9 fights that KM Promotions put on having done the same in Torquay and Wiltshire over last few years. Knockouts, stoppages, ugly mauls, passionate and boisterous fans who've bought tickets from their mate who's up in the ring getting hit, no breaks for TV, £30 tickets very close to the ring, rough women outside the ring and slightly rough women carrying ring cards about it's all there. If you've never been to a small hall show get down to your local town hall and take your mates because you're missing out.
Agree with you there mate. I like the echo arena here in liverpool, but its just not quite the same as going to shows at the olympia for instance many of the reasons you mention.
