Intersec missions

With CIG gating the TSG now behind rnak 3 intersec Ive been trying to get my rep up.

Unfortunately with the changes I cant seem to kill, or even scratch the paint on anything.

I have a Superhornet Mk2, with 4x NDB 30's and 2x Deadbolt on the wings. Did a patrol, and got the one that spawns 5+ guys.

1x 400i, 2x Cutlass and 2 other ships. After dumping endless rounds into a cutlass it didnt die (literally focus fired a single cutlass with my NDB's for about 2-3 minutes and got a tiny red mark on the target picture), I couldn't do any damage to the other 4 ships and got blown up eventuality to a powerplant failure.

What ships should I be buying and bringing to do these missions now with the changes to armor? Before I would show up in my SH with 2x revenant and 4x tigerstrikes and absolutely annihilate everything solo. Unfortunately I only got myself to contractor and not SR Cont with rep and need a full level....but it seems I dont have any combat ships other than my SH.

Can anyone help point me to a ship I can buy (pref in game) and a weapons loadout that I can use to clear these missions?

Thanks
