I personally think, contrary to majority belief, that being able to lower and use the bridge is a much higher priority because just being able to lower the bridge, can enable a team to gain a vast amount of points at the end of the round. Additionally, the bump may prove harmful to any unprotected electronics/mechanics underneath the robot. Plus, there is always the possibility that the robot my become stranded balanced on top of the bump (unless it is designed to not do so).
Hope this helps.
