On a monopod many people are happy with just being able to tilt the lens up and down because side to side movements can be made by simply turning the monopod. So most people seem to forgo the ballhead on a monopod. To tilt the head up and down there is the MPA1 from Kirk:
You pay more for each upgrade in sturdiness. If you don't need to tilt the head up and down--as is common for sports shooters--then simply mounting a quick release clamp on the monopod can work very well and is a common solution.
So although the M10 is a great ballhead for a tripod, I can't see how it would be that useful on a monopod. If you need to tilt the lens up and down I would go with one of the monopod heads listed above, but if you don't then I would just mount a clamp on the monopod. I hope this helps.
