Wouldn't bumpers be a hindrance when trying to get across obstacles like a 4" by 4" on the ground or some stairs? Next year there has to be rougher terrain as part of the challenge (no, not water

). It seems that bumpers would not be so good in those situations.
We did not use any bumpers this year because we decided that instead we should reinforce the chassis some more, which we think helped us by having one less thing to worry about on the field.
