I think the second half is even more true than the first sentence. It is necessary to figure out when to strike the target at all, since the Viktoria's are quite fragile and cannot take a lot of hits until Vanessa will pop up. Most of the games I played in the past I went quite agressively forward and ended up in trying to get a Draw out of the game. In the end, the speed of pressing forward is determined by strategies, schemes and enemy.
I find that one Ronin is enough to be taken into the crew. I try to field other models. In the last game, I had one Ronin, one Student, one Gunslinger, Von Schill and the Librarian. It often depends on the enemy, which models to take, though having a variety to choose from is essential, since there are not a lot of synergies between the Outcasts minions (except for SoC/Viks or Von Schill/Freikorps).
I am still in the progress of figuring out a great tactic, but it mostly depends on the situation you are in. And that you will learn by playing and experimenting. Since I am still in that stage, I am not much of a help; but taking a breath and thinking before a charge and whether it is necessary is even more important. And the game is about objectives (strategies and schemes) rather than killing the opponent.
Well, but then you have 10SS+ in your Deployment zone, while your enemy is attacking 2/3 of your Crew in a 30SS game. I have never tried it but I find it quite difficult to handle the enemy then.
