Non-Cylindrical Bumpers?

Our team has been unable to find any cylindrical pool noodles in stores and was wondering if we are aloud to use a flower-shaped pool noodle on the robot (I am told it somehow satisfies the 2 1/2 inch diameter for a noodle).

Thanks,
Team 818

p.s. Already submitted in Q&A, just looking for an unofficial answer from someones previous experience with bumpers.

Try Pools and Spas A-Go-Go on 12 Mile in Berkley. We got ours there, about 3 weeks ago.
