Actually, we ran the light ones like the one in the Parma package. To make it last just be sure you get all the way off the narrow bands with the wiper button at full throttle. We rigged a second wiper over the full throttle band to trap the moving wiper and maintain firm contact. It is surprising how little time you spend at part throttle, especially in stock. My friend Tim Neja actually reversed his and used the long end for brake and the short end for throttle to get quicker response.
