I agree with DG. In Goons slogs you need to reach $6 for more Goons, $5 for Duchy and try to get some $8s for Provinces as well. So you need as much Silvers as you can get to dilute the incoming Curses and Coppers (eventually you are going to start buying Coppers for points with Goons, but don't do it too early because it will hinder your hability to buy more Goons). Especially since you won't be getting too much Gold due to Goons competing at $6.
EDIT: Without much thinking, I would open 2*Silver (or Mountebank/nothing) and then go more or less Province > Goons > Stables > Silver, eventually switching Stables or Goons for Duchy and start buying Coppers with Goons.
