I found a piece left on a table the other day. Based on all the bad press i've seen on this little cube i thought i'd give it a work-out. Verdict? It works fine. Yes its a little different texture than my usual Master(no big deal) but i never miscued(i chalk about every other shot) . I know that ChampionshipBilliards now owns SC and i've heard they may be coming out with a new formulation. Don't hesitate to try it, good basic chalk that does its job.
