I hear ya, man. On Thursday, I had some time to get into a nice ring game after league play. Same exact thing -- *one guy* was using this Kamui Chalk, and the cue ball was a mess. It looked like a blue version of a measle ball. And, before long, this was transferring to the object balls! Mind you, this is a nice pool hall, with Gold Crown IIIs impeccably maintained (the Joss tour stops here), and the balls cleaned or polished after every customer's use. So it's not like we were "pinning" normal built-up wear and tear from multiple customers on this guy. Nope, those balls either get wiped down by hand, or go into the polisher after each customer turns them in.
The rest of us in the ring game (who were not using Kamui Chalk obviously) wanted to strangle this guy, because the balls were skidding like crazy after that. We FORCED him to use either Masters, Blue Diamond, my Russian Magic Chalk, or, gosh, anything but that Kamui stuff. And he didn't play any better or worse after that, either. Talk about a placebo!
I don't care how good this stuff is -- it very quickly (and I mean, VERY quickly) makes a mess on the balls.
Plus, who wants to have to alter their pre-shot routine, to include a "counting regimen" of shots *not* to chalk prior, to avoid "using the Kamui Chalk too much"?
