I would say that given a level playing field for all competitors that it is a lot harder to reach and represent England at the Europeans in the classic class than it is to get to represent England at world level in world style ploughing, however the reverse applies when it comes to actually competing in the above competitions, it would be a lot harder to win the World style ploughing at world level than win the European in classic ploughing.
However with Will being Welsh the path to either could be a bit easier, not due to lack of skills in Wales just less competitors in either class
Said it on numerous occasions - as far as England goes it's not winning the Euopean, it's getting there that's the tricky bit.
