We used long rollers with latex flaps at BAE, which did not work well at all. We changed to vacuums for our week 2 regional at WPI and we were unparalleled in our ball possession. However, the ball had to be centered as we drove into it in order for us to gain possession. We were able to go around anybody once we got possession, using our swerve drive at full speed. Now we may be changing to something that's even better
. I'll hesitate to call it a roller but it's along those lines...
