i was wondering the same thing.
we actually recommend this chart for a lot of our local retailers and it has gotten to the point where there are many discs not on it- including the Whitler still .
What's the word?
The new discs for the chart are being thrown so we should have a new version soon.
Unfortunately when we switched our site to the new version we found out a whole lot of things got dropped off. We are working on getting it back on the site and I'll let everyone know it's back as soon as it gets there!
