Best Dragon Ball Farming Method No One Has Talked About

Now for the explanation. When you start the normal Great Ape Festival you start in the Sky. Go the the Pod Crash site next, there will be 3 Patrolers in training waiting there...obviously fight them for three chances at dragon balls. Afterwards go through the quest as fast as possible after beating them, after beating the three, yes 3 Great Apes, return to the sky and you'll fight three more Patrolers in training each having their own chances for dropping dragon balls. Done.

Now my personal best run I've had with this strat has gotten me four dragon balls in one run (yes, that good) but on average I usually only get one or two per run.

Hopefully this helps.

Edit: After grinding here for a bit, I realised one thing...If you look in the second condition for the ULT finish, it's 10 min, where in the first game it was 5 min...and I've always thought of this quest as 5 min to get ULT finish, so the cutting it close has been removed, due to my mis-remembering. and is easy to do as soon as you get it with three people.
