We also used direct drive this year for the first time, going to a pair of half-tracks centered along the sides for added stability in tight high-speed turns. Also, we wanted to try something different using our success in past years with tank treads.
I agree with Peter, though--a chain to the drive shaft does offer that protection from impact loads, especially with the higher-speed gearbox that we went to after our first regional. Those stresses may have transferred to the tread belts and may have been the cause of a couple stress fractures. We were fortunate that we never lost one during a match--they were found during pre-match checks.
