I favour the sort of busher than can flush on top with the same sort of commitment it flushes below,often at speed and vocal,the only mutt that meets my requirements is the Beddy and its Beddy/Fell hybrid,not suitable to some perhaps,possibly because they have yet to encounter it,IF they had they may see the light.
I dont know if it is your point, but I wasn't discounting the beddy, I merely meant the beddy whipped is more of a lurcher than a busher, I like your point though
