i actually found the site today too, and then found this thread while googling to find more information about it. it seems like weightless is the most similar to mj for a shorter one while journey is longer and more of a personal adventure. i tried weightless and actually got that nice "lifted" (weightless) feeling as well as euphoria. it wasnt a stoney couchlock feeling though, it was much more "high" and uppity, i liked it. i also did adrenaline rush and it was pretty intense, and it's only 5 minutes which is good for me because im impatient haha.
