I have been to both quite a few times, obviously living here, and think the Gabba is a much better ground. I just think that the complete grandstand holds in a lot more noise whereas at Metricon the gap as well as space under sails maybe opens it up for less echo?! Anyway, off topic, and I suppose I havent been to a 'full' Metricon yet. But regarding the NAB fixture, wrapped I'll be able to trundle down to get an early taste!
