SDP-SI sells lightweight sprockets for 5mm HTD timing belts that have a polycarbonate body and various styles of aluminum hubs. We used the 'Aluminum T-Insert' sprockets at the time (which we broached keyways into), but might consider Fairloc hubs for the future. Both of the mechanisms (the shooter and ball intake rollers) were high-speed, low(ish)-torque systems, so the lower torque capacity of HTD belts versus GT2 wasn't an issue. We didn't have any issues with the belts (or pretty much anything else) on our robot that year.
