If you are bad at everything JABO-related, like me, the best way to use rockets is just as I use bombs. 90 degree approach. When you are 90 degrees down at target, things launched or dropped from your pylons are generally going to go exactly where your gunsight is pointed. Couldn't be easier. Rockets can be a pain if you are launching from significant altitude, so always keep salvo 1, and launch a test rocket before you launch the rest. Remember with a 90 degree approach you're going to be nose on target for quite a while, so you have fully enough time to launch a test, watch it's trajectory, and then launch the rest accordingly.
