I have to chime in for this one. First of all let me say excuse me, I am not an ignoramus. 2nd I have a pool table at home and I can see the blow off that happens when we have TOO MUCH CHALK on the damn tip; call them racing strike marks or chalk specs or obstacles or what ever. My point is that this chalk crap ends up on the table, sometimes in little chunks of chalk; these things are road blocks, obstacles that I can't see that are there, and when I run over them with the cb or ob may change the course just enough to make me miss the damn shot. Did you know that little pieces of leather from your tip can end up on the table after you shape it?
In closing Excuse Me for being considerate. OH and BTW, just in case you are wondering I do feather the chalk over the tip and still I see excess chalk that need not be there.
