Double drops not so much

I was having a better drop rate on han today than chewie. Ive been simming them in groups of 3. If 1 node gives me zeroes for 2 straight tries, I switch to the other one until that also dries up. Then it's time for a break....
I really hate cantina farming! It just feels like gambling which I also hate, nothing like seeing your hard earned crystals get sucked down the cantina slot machine...
