You would be able to drop to a midwide with 11 boots, especially if your bindings are set to fairly large angles. Most midwides are in the 25.5-26.0cm width range. On manufacturer websites, you can usually highlight wide boards only, while the midwides and regular boards do not get highlighted, usually it will say in the description if its a midwide. But really you can just look at the specs. Anything 25cm and wider you should be fine.
As far as all around board recommendations, I'd say the Rome Flag and the Burton Custom are good choices. Lots of good things said about each one.
