Today I started with the 8 mm cane at strength 10 and after the first six dozen I increased the strength to MAX. After 8 dozen more I switched to the 6 mm cane and reduced the strength to 9, but increased it again to MAX later. Again I experimented with a different camera angle from the front. Twentyfour dozen strikes, 8 mm cane with strength from 10 to MAX, 6 mm cane with strength from 9 to MAX.
