One of the major advantages of Taom V10 chalk is that it does not come off on the cue ball. This is an advantage because it basically completely eliminates kicks when playing which does actually help you win. If I remember though the Kamui chalk is not like this I think it is even dirtier than Master.Last I checked Kamui is still $30 per cube. If expensive chalk does not help me win I don't see how its not a waste of money. As far as it being cleaner I'm not going to stop cleaning my table because its supposed to be cleaner, I don't seem to have a mess problem with my current chalk.
Speaking of Master, if you are going to use basic chalk why not use Triangle? It is a better chalk from the same manufacturer IMO
