I say go for the dro. Eventhough it's only one ounce whereas you could get two ounces of the midies, quality over quantiy is the best policy. In the long run, the dro would probably last just as long as the two ounces would because you don't have to smoke nearly as much to get high, which is also better on your lungs, and the high is so much cleaner and overall better. Remember my motto when it comes to herb, shitty weed makes you feel like shit.
