Solaris is the best bet. Again, solaris along with a missile firing front can be good too. That way, you will have 3 front firing solaris and a missile. Given the agility of the Bottlenose, you can quite easily wreck heavy and medium bombers with that loadout, either TS or just tank him when and where possible, in between the TS sessions.
If you point the nose at a higher angle you can fire the backfiring slots forward. If you put a missile on one of those slots you will be able to fire forward if your nose points ona 45 degree up and your missile about 20 degree down. That way you got 4 forward firing solarises 1 forward missile and 5 backfiring solarises
