to be honest I think the discussion about atmosphere is a little redundant, wherever we go away from clifton lane (new york; millmoor; DVS) will be 'soulless' compared to the lane due to comparative size and number of supporters to fill it. We will have to move sooner or later, i think that's inevitable due to new regulations/ground criteria that will follow the creation of a professional second tier.
however, the problem with DVS in comparison to the others is the running track, which for something like rugby with it's style of play (rucks, mauls, forward passes etc) doesn't lend itself to being separated from the action as would happen there.
I think New York would be difficult also due to size and the agreement that would be reached re groundsharing, which leaves millmoor as the best option but with the MASSIVE sticking point of THE GREEDY BOOTHS which makes it all but impossible.
In conclusion, who'd be a director at RRUFC?!?
