I've hippieflipped two or three times... each of which were not really that fantastic and left me wishing I'd just saved my MDMA / mushrooms for seperate experiences.
I have only had a "true" (true = not half-assed) candyflip once. And granted, I was in the best imaginable setting watching my favorite band play their last set possibly of all time. But regardless of that I think this is a much superior combination... in fact one of the very few combinations with psychedelic drugs that I would even bother with.
I took 3 blotters and was sticking my wet thumb in a bag of MDMA powder every couple hours. It was very low-anxiety, incredible visuals which got a lot brighter and more neon once the MDMA kicked in, and the MDMA also seemed to eliminate any body kinks I would have expected from eating 3 of last summer's so-so beige blotters.
But then again I prefer LSD much more than mushrooms. So perhaps if you like shrooms better you'd like the hippieflip better.
