2. start your trip with 5k aps. plan your root as that in about 3k aps you'll have a TO with drugs. take 12t, and continue.
3. remember what targets you generally saw on BB and act according to it. if there are many missions on the other direction - do the reverse. otherwise, consider doing the other half of the circle threw miola ->PU-08 ->WI->Veliance-> Olaso->Iohofa->Zeaay..maybe Uv Seti->Let too..(according to availability of missions and aps)
4. try to take all the packages to the short distances (1-3 sectors away). don't take huge packages for far away sectors.
5. do two rounds a day. 12t of drugs in each of them. explosives missions should cover those expenses, and you'll gain much more rank that way. the most efficient way to take drugs is 6t every 6 hours. but 12/12 is efficient enough.
6. don't take missions to deep-energy located SBs (as PU-08 [6,26], unless you can stack lots of missions to them (remember that they are far from FWE too, and probably small,what leads me to the next point..)
7. small SBs and planets = few missions in the BB. big SBs and planets = lot's of missions. plan your roots in a way that you will visit in most of the big BBs. it is usually comfort to travel threw them anyways.
