I tend to se my starting clamp on the outside of the frame as a back-up for the machine clamps (like the Yusuki method), the only exception being when stringing Gut as the part of the string where the starting clamp would sit forms the loop through the grommet to the next main string. If the Gut is marked or has an abrasion from the starting clamp it cause the string to break under tension around this tight loop.
