If you want to feed smaller just up the quanity some.
I agree! With boas it's more about proper size/girth, not so much as the weight itself. I tend to judge the size of smaller rats (30-50g) based on the size of their heads since their heads tend to be larger in relation to the size of their bodies. Other than eyeballing it, the only way to be sure about size is to measure your snakes diameter and then go look for rats about the same size...
