I actually agree with a lot of this, I didn't think I would coming into this thread.
As for electoral systems, I've always been a big fan of systems along the line of AMS or AV +. Under those systems, one votes for a party and a candidate. A certain number of the seats (56% I think in Wales and in Greater London Assembly) are decided by FPTP for AMS and AV for AV +. All the others are decided by the Proportional List system and these MPs don't have a constituency.
They're fairly proportional, can still result in single party and/or majority Governments and keep single member constituencies. The main disadvantage from it is the fact that it creates in effect two tiers of MPs, as some do not have their own constituencies and therefore the duties involved. While a super proportional system like STV sounds very good in theory, they often lead to fractured weak governments (Germany is the exception).
