Verified Quality Strains

I'm proposing the idea of users sharing their favorite strains, guaranteed to have good effect. Arguably the biggest obstacle when searching for flower, is finding something with good effects. Whether you're looking for a high energy cerebral Sativa, or a "chill", maybe borderline couch-lock indica, pulling the trigger on a purchase usually requires some research and looking at reviews. After all, most of us have taken the crap-shoot and ordered some "dud" strains, while just going off of the strain name and description. I'm not sure if this will gain traction at all, but by creating this thread, I'm hoping some of you will comment with your own personal, verified "Best LIT Strains" list.
