I completely agree with what ripley said above. As it stands, with a bit of careful cutting here and there, a gamer/modeller can re-arrange the 1s, 2s, 3s, and 4s already on the sheet into something different. However, it might be a nice addition to have just two 5s. 6s, 7s, 8s, 9s or at least 2x5s and 2x6s that perfectly match the three different number sets currently on the new sheet. However, that would require a slight increase in size of the sheet, so there is no real good way to do this. But just tossing that out there just in case.
