attendance - how many of them show up
Given the numbers who turn up at the "national" oval to watch a game live on a big screen, if the title does not go to the Welsh, then they should get HM.
I suspect that the criteria is based on "how many of them show up" to games in NZ.
There is a certain quality in quantity. 45-50 thousand is some quantity.
noise - how much noise do they make, singing, cheering etc
Singing - The Boyos have to win this hands down. Always have done. Welsh seem to be best at traditional singing rather than making musical noise and simple chants.
Colours - how much colour do they show, jersey wearing, face painting fancy costumes etc.
Hasn't Hong Kong Sevens (and latterly the IRB 7's circuit) got a lot to answer for?
I think that this aspect may let the Welsh down slightly as they take their rugby a bit too seriously to go way over the top with dress ups.
The French or Argies would win this one.
Gross generalisations FWIW.
In my experience both from "Foreigners" visiting here, or when I've been overseas following Wobs or club teams, I have found nearly ALL rugby tourists to be AWESOME regardless of where they come from, even Soap Dodgers.
I can't really think of seriously bad experience I've had with any rugby tourist, whether I or they have been sober or alcohol enhanced. We've always been there for the Rugby first and foremost - a common language and culture.
