So you don't know one.
Germany FAILS the 'and doesn't involve party lists of cronies and toadies?'
Any other suggestions?
Sorry, I didn't realise your question was rhetorical.
You gave a list of ideals, a list of ideals which cannot all be totally achieved as one will always impede another. Therefore I suggested a balance which is currently in operation. If you want to totally achieve all of your aims you'll be disappointed as I believe it's impossible to have 100% PR and 100% constituency based MPs.
