We argue that adding lighter $^3$He atoms to a 4He supersolid produces attractive regions for vacancies, leading to patches of higher T_c. On the other hand, the supersolid stiffness decreases in this granular state with increased 3He disorder. Both effects are linear in 3He concentration.4 pages latex file, 2 eps figure filesSuperconductivityDisordered Systems and Neural Networkstext
