I'll have a shot first then
Agree on your point 1. I suggested a a tightening of the discretionary selection with no more than 25% of squad by selector's discretion - which could have a caveate of "or at least one place" as if the 25% rule applied, they would have no discretion with a 3 person team.
On your point 2 - whilst I agree, I think that it's a little unfair to Trevor - he does know his fellrunning but perhaps is less experienced (other than armchair) when it comes to the T&F and Road gazelles and the nuances of selection policy.
On point 3 - I do not agree. I do not think it is ludicrous to have a British and/or English Fell running Champs in the current format.
I think it does throw up the best all round fell runner in Britain / England - of course I would qualify that by "out of them that contends".
By providing a mixture of distances and terrain I think it's a fair test.
But I concede that perhaps it should stay National - ie English, Welsh etc
It can be then argued that there should also be a one-off race for the British Champs. Maybe it should sit alongside the Junior Home Internationals.
For example - at Sedbergh this year, you could have the top 6 from the respective home nations, competing on an AM course in the Howgills over approx 10 mile for the title of British Champs and British Team Champs.
Make it Male and Female.
