HM, as I understand it, you can have as many 1's on defense as you want, MINUS the two 4's you have to start. Or, have NO 1's anywhere, and then you don't have to use any 4's.
[b:8a6b6a2034]As a side note, I propose we throw in the 90 A's with the 80's decade. Otherwise, none of the A's will be useable.[/b:8a6b6a2034]
