I think chalking technique is more important than chalk brand. I cringe when I see someone put the end of their cue into that crater and squeek it around for 20 seconds (and then put it chalk side down on the rail.)
Light strokes with the outside edges of the cube. And as an added bonus, your chalk almost never runs out. I play about 15 hours a week and have been using the same 2 pieces of chalk for the last year and a half. I retired the Predator (but still had a third of it left, in very usable condition with no crater) to try the Magic Chalk. I've been using it for months and looks hardly used, with just a gentle concavity in the middle.
Granted I am age 60, but the other 4 pieces of Predator and the other 2 pieces of Magic Chalk that I have should easily last me the rest of my life, if I don't get them wet.
