Either one which would survive by having a defence of not being hit in the first place due to size and manoeuvrability. Not a defence you could apply to a Cutter.For even more context, my Cobra V brings 1300, my Viper IV 2000 armor. Both multirole mission runner builds.
My other pointer with the build above would be the rather confused shield build. A thermal resist fast charge biweave is absolutely fine, but you use this in combination with resistance engineering on a small number of shield boosters to minimise recharge times. This would be in combination with a lot of hull because that shield is probably going to drop at some point (although since its back up in less that minute, that's going to be fine). What you don't want to do is stack a bunch of heavy duty boosters as you're working against the strengths of the thermal resist biweave. A reinforced high cap biweave is much more workable, but I'd suggest a class 8.
With regards to hull as well, lightweight armour should always be engineered with heavy duty, because a percentage increase of weight from zero is still zero, so there is never a good case for using lightweight there. That engineering is really for military composite or reactive armour where you're trying to save weight on what should be a manoeuvrable ship- which a Cutter is not.
