We saw a bridge constructed by another team, and it was WAY more sensitive as determined by the battery test.

We think there are missing springs or something in the drawings that are supposed to be there.

We used bungie cords underneath each side and tuned until the bridge matched the video.

Adding weight to both sides will not help. The addition of springs, or bungee cords, or similar, and fine tuning it with the battery test should make it react like a competition bridge.

A more sensitive bridge is better for practicing balancing - it is more difficult, so if you can do it with a sensitive bridge, you will find it easy with a competition bridge.

But, if your mechanism to pull it down relies on the bridge to be very easy to pull down, in competition you may find that it doesn't work well.
