It was easier to reach a consensus in the past as all the races were new to most of us. Over the years the options have become more complicated as some people have done a lot of races so rule themselves out from certain events.
There were also no decent UK events until Outlaw & Wales, now those and other new UK races are an easy option for people, this skews the decision process I think, it also has the potential to limit us reaching a decent consensus for an overseas race (except in the example of Austria 2015 which seems a special case)
It could be that given the change in dynamics we'll now struggle to get a dozen or so committing to any overseas race? Personally I dont think that should matter, its also not to say that UK, Barcelona etc are not viable options. We should be looking to explore and excite, pick races that are spepick (special and epic)
