once again, I own a couple pieces of V10 chalk, so I am willing to spend the money, no problem.My point is whether or not the consumer is being right fully charged for these chalks or not. To me, Predator 1080, or even Master, works just as well except for the frequency you have to chalk. And when players have the habit of chalking every turn or shot, well you do the math. In the meantime, I use my V10 at home on my table, and my predator or master at the pool hall cuz they don't really care one way or another.
