Are you actually using bumpers?

[Chriszuma]

I know that my team kind of brushed aside the notion of spending extra time, money and energy to add bumpers that will make our robot look less cool and less maneuverable. We also kind of figured that most teams will have them anyway, so it would be unnecessary (kind of the "If everyone else is a good driver I don't have to be" approach). We also don't feel like the 15 pounds will be anything close to a deal-breaker when push comes to shove.

Anyway, I was wondering how many teams actually are going to add bumpers, and whether or not it will affect the competition at all. Your thoughts?

(A search turned up only a 2002 thread about bumpers, not really applicable anymore)
