Where do you end up playing?

It's been a hectic couple of weeks and my one attempt to go to the club resulted in my first ever experience of a "not enough players" scenario! I wrote a little match report about the county match the other week so thought I'd reproduce a couple of the more interesting hands here. Firstly a bidding problem: where does your system get you to on this pair of hands? North is opener as unfavourable vulnerability at teams.

If you both pass West opens a weak no-trump (if North then overcalls an artificial 2 then assume East doubles showing values with some penalty interest). We lost this board in the County Match very comprehensively. A variety of -300,-130,-110 and -100 from all sides of the table.
