Hey Simon! How ya doing? Anyway, I agree, ball bots are great (I really liked 157, who, btw, won philly), but you can usually stop them. In the first match of the finals, 157 beat us by getting an incredible number of balls. We learned, and our strategy for the second match was to stop 157 from getting balls, so, in the second match, we grabbed onto the goal they had, and didn't let them pick up balls. It worked perfectly, they didn't get any balls, but then our servo broke and we couldn't unlatch from the goal to get to our endzone (less than 4 feet away!) and win. We ended up losing the match by 1 ball, (and 1 servo

).

P.S
For the finals, my favorite pairing is one really good goal bot, and a really good ball bot, then you do have a goal, and you can load it up with balls galore.
