ROGER,
I still have the discs for the KN7000 and they do work in the KN7000, however I only have about a dozen styles. I now have all 170 of them and they have been peaked and tweaked for the KN7000 and also my KN2600. I am super pleased with them.
CHUCK,
With the great imbalance in the Dollar/pound your English Money will go twice as far in the states, so it would be a great time for you to stop over and visit your family and this writer before the ratio changes
Best to all
Bebop
