I'd prefer silver/silver over feast/estate. The latter does really nothing for your economy. The former gets you pretty reliably to 5$, maybe even twice on t3/4. In addition, you have something for economy, which makes it easier to get another rebuild or a duchy. I'm not sure why he named estate on t11, e.g.
I'm also not sure why you got so many market squares. T6 is rather 50/50, I believe, but t7 8$ and two buys is either province or FG/FG, preferably province.
