SPPA (French acronym) solves both lattest problems (totally proportional and no
circumscription).
About the first problem, Montreal simulation done during the Convention of electors,
november 10th, showed direct support using four different methods
after rallying when it is used:
FPTP (no rallying) 46%
MMP (no rallying) 38% - but except to quota, proportional
STV (after rallying) 46% - semi-proportional
SPPA (after rallying) 69% - integer optimal proportional

Just read and ask...
