Hey guys, I had a full bag and decided that since I don't fight at the Gyms...because I am more interested in catching and leveling up. So what I did was deleted all potions and diamonds so that I can carry more in my pack. Look at the upper left screenshot above. I am carrying 181 red balls, 51 blue, and 51 black. No money spent and I win all around, because I never run out of balls. Good luck and try this out if you don't fight at the gyms.
