Personally, I find "The Chip Rack" to be the most reliable tool us chipper have. As far as I am concerned, it is the Bible and I refer and rely upon it 99.99% of the time. The only disagreement I have with it is the undervaluing of the LaRue Chips,

In any case, at the convention, I bought a tube or Hard Rock chips for face value--including 2 playboy chips. The "bible" is correct.
