I'm all for companies trying to make "lighter" versions of things.
But this is just wrong. A travesty along similar lines to the Mars Delight or the Kinder Bueno. The only acceptable chocolate / wafer combination is the KitKat in my opinion (which is the only one that counts on my blog).
As for the confectionery versus biscuit debate...I used to work for the sweetie company that makes KitKats and they classified the 4 finger as a chocolate bar and the 2 finger as a biscuit. So there.
