I would mostly agree with that statement. I definitely would say the equal amount of headies will be significently stronger, but NOT significently stronger to outweigh the price difference. Around here (a part of california), an ounce of shake is like $25-$50. An eighth of bud is $25-$50. So you get 28 grams or 3.5 grams. Now the 3.5 grams is more potent for sure, but is it 8 times more potent? Certainly not.

I have always had better results cooking with large large amounts of shake and trimmings, rather then small amounts of bud. If the bud is really crappy, I would make hash out of it rather then food. I reserve food for the worst stuff. A half pound of trimmings can make a few sticks of pretty damn potent butter if you boil long enough.
