I played with Triangle chalk for what seems like forever, I liked the consistency of it over Masters. Then a friend and mentor became terminally ill with cancer and I purchased the last of his billiard belongings and amongst it was a half dozen 2 piece boxes of Russian Magic Chalk.
After trying it I actually preferred it over Triangle and now use it regularly. What I found unusual was 2 of the boxes had black wrapping and the rest had gold wrapping. By the time I realized it he had passed away so I couldn’t ask him about it. It’s really good chalk, not as messy as Triangle, coats the tip well, and while I do chalk every shot, I know those who don’t. One of those players uses it as well, and says he can go through a rack or two without fear of miscues.
