Most high end strains have a good high. You need to decide on what kind of high you enjoy, or what market you're going after. Bag appeal smell, and taste also play a big part in the experience. I've had people rave over what I thought was shit weed. It just looked good in the bag. No good high and a heavy chlorophyll taste. On the other hand, I've taken bagseed and grown it into some very nice sensi. If you can afford to, get a variety of seeds and try each one. See what you like and make an informed decision. Sure it takes time, but if u want instant gratification, just go buy a few sacks and smoke up!!!
