The distribution for the NCAA weights makes sense: 125 - 133 (8 pounds), 133 - 141 (8 pounds), 141 - 149 (8 pounds), 149 - 157 (8 pounds), 157 - 165 (8 pounds), 165 - 174 (9 pounds), 174 - 184 (10 pounds), 184 - 197 (13 pounds). The heavier weights have greater weight spans. For free, I would suggest: 60, 63, 68, 75, 84, 94, 104, 130 based on larger spans at higher weights.
