Marc is right. A roller starter is impractical particularly for LSR. Particularly Bonneville. They are awkward and require a couple of people to manhandle them in and out of a truck. A hand held starter is really the only solution. At Bonneville Joe, my crewman, starts me. He puts the starter back on the dolly, leaves it at the line and then chases me. No hold up of people behind waiting to run. On the way back to the pits we stop and pick up the starter. Roller starters lie shown would make you really popular with those in line.
