I have had my V10 about a week so far. What a difference vs Masters. I was a BIG Masters proponent. Still am for the most part. When you have a pre shot routine and chalk before every shot, Masters works as well as any chalk on the market. Grips, wont miscue and stays on.
However, it is messy. It leaves a lot of dust that will build up over time. I have a table in my finished basement and I can feel the dust on the floor and rails after a few hours of playing. The inside of my Diamond also had quite a bit of chalk dust in the ball return. I cleaned the table inside and out, polished the balls and cleaned my stick.
After a few days of playing with the V10 I am sold on it for the cleanliness alone, for my home table. The balls stay clean, no more gritty feel on the rails or floor.
I will say if I was only playing in a pool hall, I would just use masters as it works as well as the V10, just dirtier. The price tag while high for just "chalk" is only really obscene when compared to Masters. I will pay the difference for my home room, I would not if I didn't have a home table.
Just my opinion for what its worth.
