My local game store is having a small tourney tomorrow using missions/scenarios. I thought it would be fun to run a 3 PS9 squad with Vader, Kylo in his Silencer, and a Soontir Fel Interceptor. Will I get wrecked? What upgrades should I use?

So, given that I don't know the missions or scenarios, I have to consider the ships more or less in their own right. Now, Vader and Kylo are both very strong. Vader with VI, TIE X1, Advanced Targeting Computer, and EU, then Kylo with the title, AT, and either VI/Adv. Optics/FCS or PTL/Primed Thrusters or Threat Tracker/FCS or Adv. Sensors are both very competitive. Soontir, not so much. He's too fragile. So, along with Grandpappy and Grandson, a nice little accessory TIE, like Epsilon Ace/Leader, fits well.
