There are several brands of chalk that will work every bit as well in terms of cleanliness and friction.
I chose a brand to play with because it remains on my cue tip and even so, I chalk after every shot.
The price is about $3.00 per cube unless you buy it in bulk. You can get a carton (25 boxes - 50 cubes)
on ebay for $125 shipped. I purchased a carton years ago and I still have plenty of chalk. It stays on your
tip longer, doesn’t flake, and doesn’t make a mess for your hands, cue ferrules, shafts and cloth. I have
several brands of chalk but my all time favorite for quality, cleanliness and price is Blue Diamond chalk.
IMO, 50 cubes of Blue Diamond is a much better selection than purchasing a few cubes of TAOM V10.
