FW-190F's need the Flammenwerfer and AB cluster bombs with SD2 AP and SD4 AT bomblets as well.
The PB rockets were a late war development and quite uncommon and IMHO should not be included.
The Schlachtflieger's bread and butter for anti armour work was the bomb.
The AB containers and sub munitions would fill the tactical niche for a decent aerial anti-armour area effect weapon.
The Flammenwerfer weapons were also very effective weapons for stopping massed infantry and armour attacks. The Luftwaffe equivalent of a modern napalm strike. The attacks were conducted very similar to a torpedo bomber attack. The weapon's effective delivery was limited to a narrow speed and altitude envelope.
Adding the ER-4 bomb racks gives the FW-190F series the ability to take out 8 seperate armour targets.
I think the addition of these three weapons systems to the game would fill the "rocket niche" nicely and much more accurately reflect the tactical capability of the Schlachtflieger units. It would also add a unique "fun factor" making the FW-190F series more attractive to fly. Granted they were not quite as efficient in the armour defense as multiple rockets but they were certainly close enough to be useful.
Just my thoughts,
