There is space on the robot inspection form to weigh two set of bumpers. RIs tend to go by the inspection form & not like anything that doesn't fit on the form. You would probably get by with two sets of reversible bumpers. Absent something specific in the rules or Q&A, I think more than two sets is iffy and would depend on the LRI at the event. Insert the usual disclaimer about prior years rules.
