Hippy-flipping I prefer. I have not done it often... but when I do it turns out to be a very positive experience. Shrooms are generally more euphoric for me than acid is... and so the euphoria is able to greatly increase with the added mdma. very erotic experiences. makes me want to sing, yell, scream, cry, laugh, touch myself and just about everything else. I become very vocal. overall it is more intense also.
With candy-flipping I like to go to parties... raves... I like to dance on these doses. Although I have a sit down an talk through some things with friends while candyflipping. And that can be a very nice experience.
With hippy-flipping I feel like you don't need to over analyze things or talk too much. Instead, everything is as it should be. And you and your tripping partner somehow connect and feel the same vibrant energy without using lots of words to express it. candy-flipping requires lots of talking unless you are out dancing. It can be very therapeutic... but I feel like hippy-flipping is much more immersive and spiritual. Highly pleasurable also.
candy-flipping is awesome and is very fun... but the euphoria does not compare to the hippy-flip in my opinion.
