EDIT: to Ela
I like a Jack opening here, treasures will be pretty valuable in your deck for quite some time and if you need to get rid of them, you always have that option. You also don't have to continue playing your Jack after the Estates are gone, and Count's discard helps you cycle past treasures if you're using Watchtower for draw (which you should be no matter what your strategy is, that includes double Tactician).
As for which way to go, well I think deciding that before the game starts would be a mistake. It could be that you go for a Festival/Watchtower deck that ignores Tactician because you want to go for Vineyards, that deck seems really good. You could also go double Tac plus a million awesome enablers and that deck is really good too. Festival is key for both of these decks, and multiple Counts are probably good as well. Your draws should probably dictate which direction you go in.
The fact that the things you want a lot of ASAP cost $5 makes me want the Jack in the opening quite a bit more. Your deck can do lots of stuff before it gets super-ultra thin and Jack doesn't actually hurt you in your quest to get super-ultra thin, you just stop playing it if you don't want the Silver more than you want to draw cards or whatever else Jack gives you. Hitting $5 early and often is so important here, and if you decide you want to pile Provinces, the Silvers are sometimes very welcome.
There are cases where you may not want to go for Vineyards, I think in your game you were right to go for them when you did, of course, but I don't think that you can say "yes Vineyards for-suresies 155% 4lyfe" before T1 of the game. This board is really interesting, there's a lot going on.
